Speaker:**Noah Wilson, title: The Realizability of Graphs in Higher Dimensions**Wednesday, November 4, 2015, 4:00 PM, Lockett 284: Speaker: Sean Taylor, title: Sheaves of Manifolds.**Abstract: "In the mid 20th century, Grothendieck had the insight that geometry is best described as a topological space with extra structure - most commonly which functions live on the space. This led Serre and Grothendieck to use Leray's theory of sheaves on topological spaces to greatly abstract and generalize earlier work in algebraic geometry. Today, sheaves have found use in any setting where geometry and topology are used. They are a high-powered tool with which every mathematician should at least have some familiarity. In this talk, we will explore the basics of what a sheaf on a topological space is and see some examples of them and their uses."

Title:*What do I learn if I decide to compute integrals?*Abstract: The study of the evaluation of definite integrals is full of surprises. This talk will present some of them in relation to Dynamical Systems, Number Theory, and Combinatorics. The first example deals with the rational integral \[N_{0,4}(a;m) := \int_0^∞ \frac{dx}{(x^4+2ax^2+1)^{m+1}}.\] The numbers \[d_l(m) := 2^{−2m} \sum_{k=l}^m 2^k {2m-2k \choose m-k} {m+k \choose k} {k \choose l} \] play an important role in its evaluation.

The sequence $\{d_l(m) : 0 ≤ l ≤ m \}$ has many intriguing properties, some of which remain to be decided. (=*Looking for collaborators*).

Here is a nice non-linear dynamical system \[ \begin{split} a &\mapsto \frac{ab+5a+5b+9}{(a+b+2)^{4/3}}\\ b &\mapsto \frac{a+b+6}{(a+b+2)^{2/3}}\\ \end{split} \] Where do these formulas come from?**Integrals, of course.****Friday, March 27, 2009, 2:00PM, Keisler Lounge Lockett 321.**Math 4???: Don't know which 4000 level math course you want to take?

Unfortunately, some of these obvious results turn out to be quite false! As a result, we'll see why mathematicians blab so incessantly about proofs.**Wednesday, March 18, 2009, 3:40PM, Lockett 285.**Mark Sepanski, Baylor University Mathematics,*Just Can't Stop Counting.*Abstract: We all begin our mathematical life by studying the integers. And while the integers are pretty cool, you can only multiply so many seven digit numbers before you call it quits and move on to the rational numbers. After that, you hit the real numbers and eventually move on to the complex numbers. But what comes next--if anything? In this talk we'll give one version of the answer to this question.**Friday, March 13, 2009, 3:40PM, Keisler Lounge Lockett 321.**π Day's Eve celebration. We will construct π, learn about its history, and eat pizza and pies.**Friday, March 6, 2009, 3:40PM, Keisler Lounge Lockett 321.**Regular Math Club meeting with food and math.

Using state-of-the-art 3-D animation, the film guides viewers through the zero-punctuated pattern [of the zeta-function] that Riemann unveiled. It also describes the friendship between G. H. Hardy and Srinivasa Ramanujan and the difficulties both men experienced as they confronted problems in number theory." (from the DVD jacket)**Friday, January 23, 2009, 3:40PM, Keisler Lounge Lockett 321.**We will begin by discussing teachNOLA, a selective Teaching Fellows program that recruits and trains committed individuals to teach in New Orleans public schools, using handouts by Ashley Angelico.

Poster for Zagier talks.**Note the special days, locations and times.****Tuesday, April 22, 2008, 3:40PM, 239 Lockett.**Professor Tara Brendle from the LSU math department presented a lecture entitled "Braids and Cryptography". Professor Brendle is an expert on topology, which is the mathematical study of properties of seemingly different objects that are really the same, in a generalized sense. For example, a coffee cup and a donut are the same in a topological sense, because they both have one hole. Topology is one of the principal areas of pure mathematics, and it has also been used in physics and other applications. This talk was accessible to undergrads. (Abstract: In the late 1990s Anshel, Anshel, and Goldfeld proposed a new cryptosystem based on Dehn’s famous “Decision Problems” in combinatorial group theory. Their paper sparked a great debate about the effectiveness of such a cryptosystem which continues today. In this talk, we will take no sides in this debate! We will describe the particular group which Anshel, Anshel, and Goldfeld suggested for use in their cryptosystem, known as the*braid group*. This group is widely studied by topologists because of its close connections with knots and surfaces. We will also show how to implement the Anshel–Anshel–Goldfeld cryptoscheme using braid groups.) Refreshments were provided.**Note the special day, location and time.****Tuesday, April 15, 2008, 3:40PM, 130 Howe-Russell Geosciences Complex.**Professor Hyman Bass, who is a National Medal of Science Laureate from the University of Michigan, presented the lecture "Cake Sharing, Euclidean Algorithm, and Square Tiling of Rectangles" that was accessible to all undergraduate math majors. The abstract of his talk is as follows: [This talk answers the question: If you want to equally share c cakes among s students, what is the smallest number of cake pieces required? It makes interesting connections with all the topics in the title.]**Note the special day, location, and time.****Thursday, March 13, 2008, 4:30PM, 232 Lockett.**Professor Guoli Ding gave a totally awesome talk entitled "Solving Linear Inequalities with Applications to Geometry, Optimization, and Combinatorics" that was very accessible to undergrads. (Abstract: Since every equation $A = B$ can be equivalently expressed as two inequalities $A ≤ B$ and $B ≤ A$, solving inequalities can be considered a generalization of solving equations. In this talk, beginning with a very simple algorithm, we develop a general theory on solving linear inequalities. Then we will discuss applications of this theory in different areas of mathematics, including polyhedral theory, linear programming, and combinatorics.) Refreshments were provided.**Saturday, March 8, 2008, 10AM-3:45PM, Tureaud Hall.**The LSU Math Contest for Louisiana High School Students was held.**Friday, February 29, 2008, McNeese State, Lake Charles.**LSU sent two teams to compete in the "Student Team Competition" held at the meeting of the La-Miss section of the MAA.

The scores for the top 4 teams were: Mississippi State 133/150, LSU 131/150, Ole Miss 114/150, Tulane 113/150.**Wednesday, February 27, 2008, 3:40PM, 130 Howe-Russell Geosciences Complex.**Professor Richard A. Askey from the University of Wisconsin presented a lecture entitled "What is Ptolemy's theorem and why is it useful to know a few different ways to prove it?" that was accessible to all undergraduate math majors and any students who had a good high school geometry course. Here is an abstract of the talk: [Ptolemy was best known for his astronomy work, but his book on this contains an important theorem in geometry which is still of interest. The theorem deals with quadrilaterals inscribed in a circle, and was important to Ptolemy as a tool to construct what we would call tables of values of trigonometric functions. We know better ways to do that now, but Ptolemy's theorem is still important, both as a way of learning important ways of attacking some geometry problems, and because of other uses of it. A number of proofs will be given, including Ptolemy's geometric proof, Euler's proof using the law of cosines, a combination of these two proofs to extend Ptolemy's theorem to general quadrilaterals, and ways to reduce this problem to a simple problem on a line.] Professor Askey is a member of the National Academy of Sciences. Refreshments were provided.**Thursday, February 21, 2008, 4:30PM, 232 Lockett.**Peter Wolenski, Russell B. Long Professor of Mathematics at LSU, presented a lecture entitled "Nonsmooth Analysis: The Mathematics of Optimization" that was very appropriate for undergrads and beginning grad students in economics, engineering, and math. (Abstract: Nonsmooth analysis is the study of generalized notions of derivatives for functions that are not necessarily differentiable in the usual sense. It is an important area of mathematical analysis that undergirds much of modern optimization theory. The theory of nonsmooth analysis was developed by Francis Clarke and his school in the 1970s, and has since been employed in economics, engineering, finance, and other areas. This talk will provide a nontechnical overview of this theory and a glimpse at some of the many applications in which nonsmooth analysis has had a major impact.) Refreshments were provided.**Thursday, February 14, 2008, 4:30PM, 232 Lockett.**Project Director Peggy Wang from the Baton Rouge Transition to Teaching program talked about alternative paths to teacher certification in secondary math and science for people who aren't necessarily education majors. (Abstract: Baton Rouge Transition to Teaching (BRTTT) is looking for math students who are passionate about math and who want to make a difference in their communities. Funded by the US Department of Education, BRTTT provides an alternative path to teacher certification in secondary math and science. We are looking for nontraditional candidates including graduating seniors who are not majoring in education to help address the critical teacher shortage in math and science. Through our intensive seven-week Summer Institute, we add educational theory and instructional strategies to candidates’ content knowledge. Upon successful completion of our Summer Institute, candidates can begin teaching full-time in August. Support is a cornerstone of our program; we provide specialized training to principals and mentor teachers so that they can effectively support new teachers in their first years of teaching. We also have Robert Noyce Scholarships ranging in value from \$12,600 to \$15,000 for graduating seniors who go through our program and teach in one of our partner districts for at least two years.) Refreshments were provided.**Thursday, February 7, 2008, 4:30PM, 232 Lockett.**Professor Pallavi Dani from the University of Oklahoma Department of Mathematics presented a lecture entitled "Wallpaper Groups" that was very appropriate for undergrads. (Abstract: Anyone who has redecorated a room knows that choosing between the hundreds of wallpaper patterns in the store is a daunting task. In this talk I hope to convince you that the number of distinct wallpaper patterns is surprisingly small.) Refreshments were provided.**Thursday, January 31, 2008, 4:30-5:00PM, 232 Lockett.**This was our general interest meeting where we discussed the activities for the coming semester. We planned some totally awesome math club talks for this semester, plus we decided to send at least one team to the Annual Meeting of the Louisiana/Mississippi section of the MAA.

### Fall 2007

**Friday, December 7, 2007, 1:00-3:00PM, Keisler Lounge (321 Lockett).**There were poster presentations by the Fall 2007 Math 4020 students. The research topics included "Time series analysis of human gait data", "Modeling and calculating the effects of Granulated Activated Carbon (GAC) filtering", and "Optimizing production and distribution of calcined coke with CII Carbon". All math majors were invited to hear about these projects and enjoy the light refreshments. Poster for Fall 2007 Math 4020 presentations.**Thursday, November 29, 2007, 5:00PM, 232 Lockett.**There was a meeting about Research Experiences for Undergraduates (REUs) where we heard about possible paid summer research jobs. The meeting featured a presentation by Cecil Taylor Alumni Professor Robert Perlis who is one of the three LSU professors who organize the LSU REU. Check https://www.ams.org/programs/students/emp-reu for more information about REUs. Recent REU students were on hand to answer questions.**Note the special time.**Abstract: The United States National Science Foundation (NSF) funds many research opportunities for undergraduates through its REU Sites program. An REU Site consists of a group of ten or so undergraduates who work in the research programs of the host institution. Each student is associated with a specific project, where he/she works closely with faculty and other researchers. Students are granted stipends and, in many cases, assistance with housing and travel. Undergraduates supported with NSF funds must be citizens or permanent residents of the United States or its possessions. The speaker will give advice on how to apply for REU jobs.**Thursday, November 15, 2007, 3:40PM, 285 Lockett.**Professor Bin Li from the LSU Department of Experimental Statistics gave a talk entitled "An Introduction to Data Mining" the abstract of which was as follows: Recently, data mining has been attracting more and more attention in statistics and mathematics. This presentation will start with some motivating examples from real applications. Then I will introduce some of the latest data mining methods and illustrate them in the examples. Finally, I will discuss some challenges and opportunities specifically for mathematicians and statisticians to dive into this area.**Thursday, November 8, 2007 at 5:00 PM, 232 Lockett.**Professor James Madden presented a talk entitled "Conservation of Momentum: Euclid, Newton and Noether". Abstract: The key idea of Euclid's proof that triangles with equal bases and equal heights have the same area was used by Newton to prove the conservation of angular momentum. At a deeper level, both proofs are about symmetry. This talk tells the story of all of this—and more.**Thursday, November 1, 2007 at 4:30PM, 232 Lockett.**A number of people teaching Spring 2008 4000-level math courses gave brief presentations about their courses. Speakers included Profs. Cochran, Ding, Lax, Perlis, Sundar, and Vertigan and Postdoctoral Associate Seva Joukhovitski. This was followed by our math club elections. The following people were elected: Brad Johnston (President), Josh Moulton (Vice President), and Ge Mu (Advertising Chair). The positions of Secretary/Webmaster and Treasurer are currently vacant. All interested undergrads were invited if they did not have class at that time. No RSVP was necessary. Refreshments included pizza.**Thursday, October 25, 2007 at 5:00 PM, 232 Lockett.**Professor Alex Iosevich from the University of Missouri-Columbia presented a math club lecture entitled “The Cauchy–Schwarz inequality or… if the elephant is fat, then there must be a way to place a mirror to make this obvious…” that was easily understandable to undergrads and also appropriate for first year grad students. Professor Iosevich is a very well known expert in combinatorics and harmonic analysis, which are two of the most central and fast growing parts of pure mathematics. Combinatorics deals with problems like counting the number of possible ways to do complicated tasks. Professor Iosevich has more than 50 publications including papers in the Duke Mathematics Journal (which is considered one of the most prestigious pure math journals) and has given many important lectures including an Invited Address at the October 2007 American Mathematical Society meeting in Chicago. He gives great talks. All interested undergrads and grads were invited if they did not have class at that time. No RSVP was necessary. Refreshments were provided. (Abstract of talk: We use the Cauchy–Schwarz inequality to see that if the set occupied by the elephant in three dimensions has large volume, then at least one of its projections onto the coordinate planes has a large area. We then explore a similar question in higher dimensions, encountering fascinating analytic and combinatorial objects along the way.)**Thursday, October 18, 2007 at 1:40PM [sic.], 232 Lockett [sic.].**John Etnyre, Associate Professor of Mathematics at Georgia Institute of Technology, presented a math club talk entitled "Knot Colorings—From Grade School to Grad School (and Back?) in One Hour" that was understandable to undergrads and first year grad students. It was an excellent opportunity for students to get a general idea of what topologists study. Professor Etnyre is a very well known expert in the field of low dimensional topology which is one of the most central and fast growing parts of pure mathematics. Topology is also important in the study of dynamical systems and theoretical physics. Etnyre has published in the Annals of Mathematics (which is widely regarded as one of the most prestigious pure mathematics journals) and is a recipient of an NSF CAREER award which is also very prestigious in topology. He gives excellent talks. All interested undergrad and grad students were invited to attend his talk if they did not have class at that time. No RSVP was necessary. Refreshments were provided. (Abstract of talk: Knots in strings and ropes have fascinated people for millennia but have only been a subject of serious mathematical inquiry for the last century or so. Their study is now a fundamental and central part of low-dimensional topology and string theory indicates they might, in some subtle and deep way, be related to how the universe works! After a brief introduction to knots as mathematical objects, I will discuss one of the simplest ways to study them, that is by coloring them. Yes, that’s right, by pulling out your good old crayons and coloring (but of course we will need a few rules about how to color to make this useful). Once we see that this simple idea can be surprisingly powerful, I will discuss how it is in fact related to the fairly sophisticated notion of representations of the fundamental group of the knot complement. (I will define and discuss all these notions.) This is a great example of the common theme in low dimensional topology that one can frequently take fairly sophisticated things (like representations, group actions, holomorphic curves…) and turn them into a fairly simple (combinatorial) thing (like colorings, polynomials, convex polygons…). This interaction between the sophisticated and the simple is one of the beautiful and appealing things about low dimensional topology.)**Thursday, October 4, 2007 at 4:30PM, Keisler Lounge.**Professor Leonard Richardson, Herbert Huey McElveen Professor and Director of Graduate Studies in Mathematics at LSU, gave an informal presentation about applying to graduate school in mathematics.

### Spring 2007

**Thursday, May 10, 2007 at 11:00AM.**The Mathematics Consultation Clinic presented a poster session in the Keisler Lounge based on this semester's Math 4020 capstone projects. The projects involved joint work with the William Olefins Company and the Kinesiology and Civil Engineering Departments at LSU. The poster session was followed by student talks at 11:30AM. Light refreshments were provided.**Thursday, April 26, 2007 at 5:00PM.**Geaux Teach Program Manager Sharon Besson gave a presentation about LSU's Secondary Teacher Preparation Program. (Abstract: The Geaux Teach program was modeled after the UTeach program developed at the University of Texas at Austin. This new model is based on apprenticeship, much like that found in other professions such as the medical profession. Prospective teachers get their undergraduate degree in their content areas with a secondary education concentration. In the Geaux Teach program, the teaching of teacher candidates has become a collaborative effort between content area researchers, education professors, and practicing mentor teachers. The heart of the apprenticeship program is the step courses: three of the four education classes are paired with a 1 hour lab run by a content area research professor; the course + lab includes 40 hours in a high/middle school classroom observing, tutoring, teaching and being mentored by a high/middle school teacher. These classes are taken in the three semesters leading up to student teaching, and step up the level of teaching each semester. In their education class students learn theory and pedagogy, including how to appropriately use technology and how to teach in culturally diverse settings. Further information will be available at Besson’s lecture.)**Thursday, April 19, 2007 at 5:00PM.**Professor Paul Saylor from the LSU Center For Computation and Technology presented a lecture entitled "Numerical Analysis: Do Computers Really Compute? Who Knows? Google? YouTube? Math Knows" that was of broad interest to undergraduates. (Abstract: Come one, come all. See the amazing powers and wondrous skills of numerical analysis. See before you (1) a math problem discover sensitivity on a railroad bayou; (2) proof that it’s smart to approximate; (3) a computer compute an uncommon conundrum; and (4) a mighty matrix meet its match when it fails to resist relentless recursion.) Professor Saylor is an excellent lecturer and a distinguished scholar who has made very important contributions to computational mathematics, so we really appreciated his presentation.**Tuesday-Thursday, April 10-12, 2007 at 3:40PM each day.**Richard V. Kadison, Kuemmerle Professor of Mathematics, at the University of Pennsylvania gave a series of lectures entitled "The Pythagorean Theorem from Another, Slightly Sophisticated, Point of View" in 130 Howe-Russell Geoscience Complex that were of interest to undergraduates.**Thursday, March 29, 2007 at 5:00PM.**Rick Barnard who is an advanced mathematics PhD student in the area of control theory presented a lecture entitled "What Is A Control System?" that was accessible to undergraduates who took a differential equations course. Roughly speaking, a control system is a generalization of a differential equation that has a term called a control that can be chosen to influence the behavior of the dynamics. Barnard gave an overview of the issues that arise when choosing controls and mentioned some important applications. Some especially interesting control theory links include http://ieeecss.org/ and the LSU math control research page. Control systems theory is one of the most important areas of applied mathematics and engineering. Barnard's talk and the pizza were both great!**Saturday, March 24, 2007.**The LSU High School Mathematics Contest took place.
