Fall 2017

  • MATH 4997-1: Vertically Integrated Research: Combinatorics and geometry of flag manifolds
  • 12:00-1:20 T Th
  • Instructor: Profs. Achar and Sage
  • Prerequisites: Math 4200 and 4153
  • Text: notes to be distributed in class
  • A flag manifold is a generalization of projective space (the set of lines in a vector space) and of Grassmannians (the set of linear subspaces of some fixed dimension). Flag manifolds have rich connections to representation theory and combinatorics, especially through classical 19th century problems of enumerative geometry that are collectively known as "Schubert calculus." In this course, we will study both classical and modern aspects of this theory, including recent work on invariants of Schubert varieties.
  • MATH 7001: Communicating Mathematics I
  • 3:00-4:50 T Th
  • Instructor: Prof. Oporowski.
  • Prerequisite: Consent of department. This course is required for all incoming graduate students. It is a lab course meeting for an average of two hours per week throughout the semester for one-semester-hour's credit.
  • This course provides practical training in the teaching of mathematics at the pre-calculus level, how to write mathematics for publication, and treats other issues relating to mathematical exposition. Communicating Mathematics I and II are designed to provide training in all aspects of communicating mathematics. Their overall goal is to teach the students how to successfully teach, write, and talk about mathematics to a wide variety of audiences. In particular, the students will receive training in teaching both pre-calculus and calculus courses. They will also receive training in issues that relate to the presentation of research results by a professional mathematician. Classes tend to be structured to maximize discussion of the relevant issues. In particular, each student presentation is analyzed and evaluated by the class.

  • 10:30-11:20 MWF
  • Instructor: Prof. Long.
  • Prerequisites: Math 4200 or equivalent
  • Text: Abstract Algebra, 3rd ed; Dummit and Foote, Wiley 2003.
  • This is the first semester of the first year graduate algebra sequence, and covers the material required for the Comprehensive Exam in Algebra. Topics will include group actions and Sylow Theorems, finitely generated abelian groups; rings and modules: PIDs, UFDs, finitely generated modules over a PID, applications to Jordan canonical form, exact sequences.
  • MATH 7230: Modular Forms.
  • 1:30-2:20 MWF
  • Instructor: Prof. Tu.
  • Prerequisites:
    1. Math 7210 (Algebra), Math 4036 (complex analysis) or equivalent are very helpful. You should be comfortable with meromorphic and analytic functions, groups, group actions and Galois groups (definitions and examples).
    2. Know how to use a computer.
  • Text: There is no required text, but the following references and web sources are useful.
    1. Introduction to Elliptic Curves and Modular Forms (GTM) by Neal I. Koblitz
    2. Modular Forms by T. Miyake.
    3. Explicitly Computing Modular Forms by William A. Stein.
    4. A First Course in Modular Forms (GTM) by F. Diamond and J. Shurman.
    5. Lectures on Modular Forms and Hecke Operators by Kenneth A. Ribet and William A. Stein.
    6. Introduction to Arithmetic Theory of Automorphic Forms by G. Shimura.
  • Classical modular forms appear naturally in connection with problems arising in many areas such as number theory, geometry, differential equations, physics and so on. Modular forms play a central role in the development of number theory. One of the reasons is because they have very tight connection with elliptic curves and Galois representations. All the arithmetic properties of elliptic curves, modular forms, and Galois representations are extreme important in Weil's proof of Fermat's Last theorem.

    The aim of this course is to cover the classical theory of classical modular forms. The course will begin with basic definitions and examples. In the later of the semester, we will discuss some applications, advanced topics, and open problems, depending on audiences' interests.

  • MATH 7260: Homological Algebra.
  • 1:30-2:50 TTh
  • Instructor: Profs. Achar. and Sage.
  • Prerequisites: Math 7211 and 7512 or permission of the instructor
  • Text: Gelfand and Manin, Methods of Homological Algebra.
  • Homological algebra is a branch of algebra that developed in the mid-twentieth century as a way to systematize and abstract techniques from algebraic topology involving homology--a procedure in which a sequence of abelian groups or modules is associated to each object in a given category. Its influence has expanded far beyond its primarily topological origins, and it is now a fundamental tool in areas such as representation theory, algebraic geometry, and number theory.

    In this course, we will develop homological algebra in a modern, algebraic way with a focus on the language of derived categories. We will discuss various applications with a particular emphasis on sheaf cohomology. This course will provide much of the background material needed for the geometric representation theory class Math 7250 that will be offered in the spring.

    2. Functions of bounded variation; Riemann-Stieltjes integral.
    3. Lebesgue measurable sets, functions (Egorov's and Lusin's Theorem), the Lebesgue integral.

  • MATH 7360: Probability Theory.
  • 12:30-1:20 MWF
  • Instructor: Prof. Ganguly.
  • Prerequisites: Familiarity with Measure theory (Math 7311) is desirable but not required. However a good mathematical maturity and a solid understanding of undergraduate analysis at the level of Math 4027-4032 is important.
  • Text: None
  • The course is a self-contained introduction to modern probability theory. It starts from the concept of probability measures,random variables, and independence. Several important notions of convergence including almost sure convergence, convergence in probability, convergence in distribution will be introduced. Well-known limit theorems for sums of independent random variables such as the Kolmogorov's law of large numbers, Central Limit Theorem and their generalizations will be studied. Sums of independent, centered random variables form the prototype for an important class of stochastic processes known as martingales, and therefore play a major role in probaility and other areas of mathematics. A main part of the course will be devoted to understanding conditional probability and building the basic theory of martingales. Brownian motion is an important example of a continuous-time martingale. Its basic features will be briefly discussed. The course will not have any fixed text book, but some books will be cited for reference. It is important that the students take and read the class notes carefully.

  • Prerequisites:
  • Text: Instructors Notes.
  • This is an introductory course on uncertainty quantification (UQ). Uncertainty quantification is interested in how to deal with uncertainty in realistic applications, which has received much attention in both academia and industry. The main mathematical model will be partial differential equations subject to uncertainty, where the source of uncertainty includes physical coefficients, initial/boundary conditions, forcing, etc. In this course, we will introduce numerical strategies to deal with typical problems in uncertainty quantification.

  • MATH 7490: Matroid Theory
  • 2:30-3:20 MWF
  • Instructor: Prof. van Zwam.
  • Prerequisites: Consent of department.
  • Text: Matroid Theory, second edition by James Oxley, Oxford University Press.
  • Matroid theory is the study of abstract properties of linear dependence. Matroids arise from finite sets of vectors, graphs, error-correcting codes, algebraic field extensions, projective geometry, optimization algorithms, and more. In its study, the influences from graph theory and from finite geometry are especially prevalent: connectivity and minors are key concepts from the former, while collinearity and span are key concepts from the latter. In this course we will introduce matroid theory, and gradually work our way up to some very recent results.
  • MATH 7510: Topology I
  • 9:00-10:30 TTh
  • Instructor: Prof. Vela-Vick.
  • Prerequisites: Advanced Calculus (Math 4031)
  • Text: Topology (2nd Edition), By James Munkres
  • This course is a preparation course for the Core I examination in topology.

Topological manifolds, simplicial complexes and CW complexes will also be discussed.
  • MATH 7520: Algebraic Topology.
  • 9:30-10:20 MWF
  • Instructor: Prof. Dasbach.
  • Prerequisites: Math 7510 and 7512
  • Text:
  • This course continues the study of algebraic topology begun in MATH 7510 and MATH 7512. While MATH 7510 developed the theory of fundamental groups and MATH 7512 developed homology theories for topological spaces the focus of this course will be cohomology theory which is dual to homology theory. However, one of the advantages of developing cohomology theory of spaces is that they are naturally equipped with a ring structure.

    The course will be mainly based on Hatcher's book Algebraic topology, and additional material that we will hand out.

  • MATH 7590: Geometry of non-positively closed manifolds.
  • 10:30-11_50 TTh
  • Instructor: Prof. Dani.
  • Prerequisites: 7210, 7512, 7550
  • Text:
  • Manifolds of non-positive curvature exhibit some surprising rigidity phenomena, that is, statements which say that under appropriate (often algebraic) conditions, two manifolds are actually isometric. Probably the most well-known of these is the Mostow Rigidity Theorem, which says that if two complete finite-volume hyperbolic manifolds of dimension at least 3 have isomorphic fundamental groups, then they are isometric.

    In this course, we will begin with the necessary prerequisites about Riemannian manifolds and Lie groups, and then spend a large part of the semester getting comfortable with symmetric spaces of noncompact type (which are the simply-connected models for manifolds of non-positive curvature). We will end with the Mostow Rigidity Theorem and (hopefully) generalizations by Gromov, Ballman and Burns--Spatzier. A good reference for this material is the book Geometry of Nonpositively Curved Manifolds by Patrick Eberlein.

  • MATH 7320: Ordinary Differential Equations.
  • 10:30-11:50 TTh
  • Instructor: Prof. Shipman
  • Prerequisites:
  • Text: Ordinary Differential Equations by V. I. Arnold
  • Courses in ODEs are often perceived as boring, or at least tedious, because of the expected nature of some of the theorems and the technical nature of some of the proofs. My intention is that this course will deviate from that stereotype, as the field is in fact fascinating, beautiful, and pervasive in science and mathematics. As a foundation for the material, I will use the classic textbook by Vladimir I. Arnol'd, which is universally recognized as a mathematical gem. We will do both linear and nonlinear ODEs. These are genuinely different areas of mathematics, as the questions that are investigated are very different in nature.

    The linear theory is sometimes considered part of linear algebra. The overarching concept is the matrix exponential and how its structure reflects canonical forms of linear operators. I will introduce the spectral theory of linear differential operators and its intimate connection with complex analysis. I also want to include some more specialized topics, such as linear systems governed by indefinite quadratic forms.

    The overarching concepts for the nonlinear theory are flows of vector fields and dynamical systems. Upon that basis, one studies diverse phenomena such as bifurcations, separation of time scales, bursting (such as in neurobiology), hysteresis, stability (this is the connection between linear and nonlinear), control systems, chaos, and strange attractors.

    Obviously, a course cannot come close to doing justice to all of these topics, and neither can one person. My goal is twofold: (1) to present the foundational rigorous theory of ODEs, and (2) to introduce a broad variety of topics in ODEs that highlight what makes the field interesting.

  • Text: Instructor's notes and research publications to be handed out.
  • This course in an introduction to variational phase-field models in brittle fracture. We will first derive variational models of fracture as an extension of Griffith's celebrated criterion. We will then derive phase-field models through a regularization à la Ambrosio-Tortorelli, and prove they convergence in the sense of Gamma-convergence. We will then review a more recent construction of phase-field models as "gradient-damage" models, and show how they can still be related to Griffith's criterion in this framework. We will finally focus on fine mechanical properties of gradient damage models with a specuial emphasis on crack nucleation.

    Throughout the course, we will use numerical simulations to illustrate various features of the models built in class. Course evaluation will be project-based.

We will learn to calculate these groups, and use them to prove topological results such as the Brouwer Fixed point theorem (in all dimensions) and generalizations of the Jordan curve theorem. Homology theory is important in many parts of modern mathematics. If time permits, we will cover the the basic ideas of cohomology as well.
