- 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.

- 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.

- 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.

- 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.

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.

- MATH 7280: D-modules
- 1:30-2:50 TTh
- Instructor: Prof. Sage.
- Prerequisites: Math 7211
- Text:
- The theory of D-modules provides an algebraic approach to the study of
linear partial differential equations. It has important applications
to many fields of mathematics, including representation theory,
singularity theory, and the Langlands program. In this theory, one
studies solutions to systems of partial differential equations in
terms of modules over rings of differential operators. For example,
when the system involves n variables and has polynomial coefficients,
the appropriate ring of differential operators is the Weyl algebra:
the noncommutative algebra generated by the linear functions
x_{1},...,x_{n} and the corresponding partial derivatives ∂_{1},...,∂_{n}.
In the first part of the course, we will study the Weyl algebra and its modules, i.e. D-modules on C^{n}. We will then discuss D-modules on smooth complex algebraic varieties; here, it is necessary to introduce sheaf-theoretic methods. A main goal of the course is to discuss the Riemann-Hilbert correspondence--a vast generalization of Hilbert's 21st problem on the existence of linear differential equations with a prescribed monodromy group--in some special cases. Time permitting, we will discuss some applications to representation theory and to the geometric Langlands program.

Then we will study an extension of the Ito theory to anticipating stochastic processes, which I introduced in 2008. The general stochastic processes arising from this new theory involve the Ito part (adapted) and the counterpart (instantly independent). A simple example of such stochastic process is given by the solution of a linear stochastic differential equation with anticipating initial condition. One application of this new theory is to analyze stock markets when investors have insider information. The lecture notes for this course, together with previous lecture notes, will be written up for a new book on stochastic integration.

The course starts with basic definitions of Lie groups and Lie algebras. We then discuss some examples. Then the exponential map, the Lie algebra of a closed linear groups, actions on manifolds and homogeneous spaces. Several examples will be given.
