Fall 2019

  • MATH 4997-1: Vertically Integrated Research: Buildings
  • 12:00-1:20 TTh
  • Instructor:
  • Profs. Achar and Sage
  • Prerequisites: Math 4200 and 4153
  • Text: Buildings—Theory and Applications by P. Abramenko and K. Brown
  • A building is a certain type of simplicial complex introduced by Jacques Tits to provide a geometric framework for studying simple algebraic groups. They have since turned out to have important applications to group theory, representation theory, geometry, and discrete mathematics. The simplest examples of buildings are (not necessarily finite) graphs with very strong regularity properties. For example, if F is a field, then the spherical building associated to SL_3(F) (the 3x3 matrices with entries in F and determinant one) is a bipartite graph with a vertex for each line and for each plane in F^3; two vertices are connected precisely when they correspond to a line contained in a plane. More generally, the building associated to SL_n(F) for n>3 is an (n-1)-dimensional simplicial complex with simplices corresponding to “flags”—chains of subspaces in F^n. In this course, we will provide an introduction to the theory of buildings, with a particular focus on concrete examples. We will also discuss various applications.
  • MATH 4997-2: Vertically Integrated Research: Invariants in Low-Dimensional Topology
  • 10:30-11:50 TTh
  • Instructor:
  • Profs. Vela-Vick and Wong
  • Prerequisites: None
  • Text: None. Suggested references will be provided during the course.
  • In recent years, research has found many interesting interactions between low-dimensional topology and contact and symplectic geometry. This has resulted in the discovery of invariants that can help us distinguish different knots and links, and explore the geometry of 3- and 4-dimensional manifolds. The study of these invariants represents a very active area of current research. In this vertically integrated research seminar, we will study some of these invariants, with a view towards computations and applications.
  • MATH 7001: Communicating Mathematics I
  • 3:00-4:50 T Th
  • Instructor: Prof. Oxley.
  • 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.

  • 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.

  • Class Field Theory is the study of abelian extensions of number fields (which may be global or local). These extensions are described in terms of arithmetic invariants such as the ideal and ray class groups. One of the main results is Artin's Reciprocity Law, which generalizes quadratic reciprocity, and can be viewed analytically as a first case of Langlands Program.

An important example would be the Lebesgue integral on the line and n-dimensional Euclidean space. Next, we will present the connection between the Lebesgue integral and the Riemann integral, and study functions of bounded variation, absolute continuity, and Lebesgue differentiation theorems. Important topics such as Lebesgue convergence theorems, product measures, Fubini's theorem and the Radon-Nikodym derivative will be covered. We will give a short introduction of Banach and Hilbert spaces and then apply it to Lp spaces. The Riesz-Markov-Kakutani theorem will be discussed if there is sufficient time. A sampler of very good books on analysis and measure theory are:
    A. Friedman: Foundations of Modern Analysis
    L. Richardson: Measure and Integral: An Introduction to Real Analysis

The formulation of the FEM, its properties, stability, and convergence will be discussed. Implementation of the FEM will also be addressed mainly via Python programming projects.

    Additional topics may be introduced depending on the interests of the class.

    Prerequisites: Some basic functional analysis and PDE theory (MATH 4340, or MATH 7386 or equivalent) will be reviewed. Prior exposure to numerical analysis (MATH 4065 or 4066) and Python would be useful but not mandatory.

  • MATH 7350: Complex Analysis.

  • 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:
  • 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 probability and other areas of mathematics. A part of the course will be devoted to understanding conditional probability which then forms the foundation for the theory of martingales. Brownian motion is an important example of a continuous-time martingale. If time permits, basic features of martingale theory and Brownian Motions 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.

  • Text:
  • In this course we provide an introduction to theory behind the design of meta-materials for the control of light. Here we develop basic ideas and intuition as well as introduce the mathematics and physics of spectral theory necessary for the rational design of meta-materials. The course provides a self contained introduction as well as a guide to the current research literature useful for understanding the mathematics and physics of wave propagation inside complex heterogeneous media. The course begins with an introduction to Bloch waves in crystals and provides an introduction to local plasmon resonance phenomena inside crystals made from nano-metallic particles. We then show how to apply these techniques to construct media with exotic properties. We provide the mathematical underpinnings for characterizing the interaction between surface plasmon spectra and Mie resonances and its effect on wave propagation. This understanding is used for design of structured media supporting backward optical and infrared waves and behavior associated with an effective negative index of refraction. Potential applications include drug delivery, optical communication, and holography.

  • In this course, we study trisections on smooth closed 4-manifolds with the goal of understanding the minimal genus of all embedded smooth surfaces representing a given homology class (The Thom Theorem). A trisection of a 4-manifold is analogous to a Heegaard decompositions of a 3-manifold. It is a cutting-edge tool that has already shown great promise in understanding and proving some of the hardest problems in 4-manifold theory. This course will benefit students who want an overview of 4-manifold constructions and want to learn how to use advanced techniques in topology and geometry to study smooth manifolds.
