On a rotating hollow sphere, there are exactly two points that don't move at all (we might call them the "north and south poles"). The sphere belongs to a large class of important topological spaces with two key features: (1) they have some (perhaps more than one) kind of rotational symmetry, and (2) they have finitely many points that don't move when the space is rotated. "Equivariant cohomology," the subject of this seminar, is a powerful tool for studying the geometry of such spaces. Using equivariant cohomology, we will explore remarkable connections to combinatorics and group theory.
This semester, we will discuss an important result from current research in representation theory called the geometric Satake isomorphism, restricting ourselves to the simplest possible case of the 2 by 2 invertible complex matrices GL2(C). Roughly speaking, this result states that representations of GL2(C) (i.e., group homomorphisms from GL2(C) to GLn(C) for any n) can be understood in terms of the equivariant cohomology of a topological space called the affine Grassmannian. The goal of this course is to make sense of this isomorphism as explicitly as possible and to come up with a new simple proof in this case. (No background in representation theory is assumed.)

The beauty of the subject is that a great deal of it requires almost no prerequisites. Thus undergraduate students who register will be able to understand and lecture on a number of topics.
One of the main goals of the course is to go over applications and relations to various areas of mathematics.

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.

- Instructor: Prof. Perlis.
- Prerequisites: Prerequisites for MATH 7290-1 are a working knowledge of groups, rings, abstract vector spaces, and fields, including Galois theory, at the level of MATH 7210 and MATH 7211.

Algebraic number theory is the study of algebraic number fields and the rings of algebraic integers in these fields. An algebraic number field is any field obtained by adjoining to the field of rational numbers a single root of a polynomial with rational coefficients. A background in algebraic number theory is essential to any student interested in algebra, algebraic geometry, arithmetic geometry, and of course number theory.
This will be a beginning course in algebraic number theory. Students taking this course will be be prepared to take the course Class Field Theory offered in spring, 2011.

Topics include: solvable groups and Lie algebras; maximal tori and Cartan subalgebras; Borel subgroups and subalgebras; Weyl groups; root systems; classification of simple groups and Lie algebras by Dynkin diagrams; weights and representations. If time permits, we will also cover the Borel-Weil theorem, which gives a geometric construction of all irreducible representations. (Note: the term "algebraic" means that the proofs will be based on methods from algebraic geometry, rather than differential geometry and analysis. However, no knowledge of algebraic geometry is needed to take this course.)

Then we will proceed to the Ito theory of stochastic integration and familiarize ourselves with the celebrated Ito lemma, a basic tool of stochastic calculus, and stochastic differentials. We will occasionally take time out to look at nearby scenery, such as Gaussian measures in infinite dimensions and infinite-dimensional stochastic analysis. Aside from this we will also look at a few applications. These will include stochastic differential equations in finance and the famous Black-Scholes formula.

- MATH 7520: Algebraic Topology
- Instructor: Prof. Stoltzfus.
- Prerequisite: MATH 7510 and 7512, or equivalent.
- Text: Algebraic Topology by A. Hatcher
This course continues the study of algebraic topology begun in MATH 7510 and MATH 7512. The basic idea of this subject is to associate algebraic objects to a topological space (e.g., the fundamental group in MATH 7510, the homology groups in MATH 7512) in such a way that topologically equivalent spaces get assigned equivalent objects (e.g., isomorphic groups). Such algebraic objects are invariants of the space, and provide a means for distinguishing between topological spaces: two spaces with inequivalent invariants cannot be topologically equivalent.
The focus of this course will be on cohomology theory, dual to the homology theory developed in MATH 7512. One reason to pursue cohomology theory is that the cohomology of a space may be given a natural ring structure. This additional algebraic structure provides another topological invariant. In developing this structure, we will study several products relating homology and cohomology. These considerations will be used to study the topology of manifolds, yielding a number of duality theorems also relating homology and cohomology, with a variety of applications.
In addition to its importance within topology, cohomology theory also provides connections between topology and other subjects, including algebra and geometry. Depending on the interests of the audience, we may pursue some of these connections, such as cohomology of groups or the De Rham theorem.
- MATH 7590: 4-Manifolds.
- Instructor: Prof. Baldridge.
- Prerequisite: Math 7512 (Topology II) or permission of instructor.

In this course we study smooth closed 4-manifolds. We will describe standard examples and study how to construct exotic 4-manifolds (manifolds that are homeomorphic but not diffeomorphic to a standard example). Along the way we will work with fundamental groups, symplectic 4-manifolds, and Seiberg-Witten invariants. This course should be interesting to students who want an overview of 4-manifold constructions and want to learn how to use advance techniques in topology, geometry, and global analysis to distinguish different smooth 4-manifolds.

- Text: K. Ueno, Algebraic Geometry 1 and 2.
Algebraic geometry has its origin in the study of solutions to systems of polynomial equations. It is of fundamental importance in a wide range of areas of mathematics such as number theory, representation theory, and mathematical physics and also has surprising applications to such fields as statistics, mathematical biology, control theory, and robotics.
Modern algebraic geometry is based on the fundamental notion of a scheme. This course will give an introduction to schemes and their geometry, with particular emphasis on motivating the definitions and constructions and providing many examples. Topics covered will include algebraic varieties, sheaf theory, affine schemes, and projective schemes. .
- MATH 7290-1: Class Field Theory.
- Instructor: Prof. Morales.
- Prerequisite: Math 7211 or equivalent, Complex Analysis (undergraduate-level should be enough), some exposure to Algebraic Number Theory (the basic number theory needed will be reviewed the first couple of sessions).
- Text: Class Field Theory, by Nancy Childress, Springer Universitext, 2009. (Available free of charge to LSU students on the SpringerLink site.)
Class Field Theory is the study of abelian extensions of number fields and more generally of global fields. It describes abelian extensions of a global field K in terms of arithmetic invariants of K such as the ideal class group of K and its generalizations. The most basic example is the description of the abelian extensions of Q as subfields of cyclotomic fields (the Kronecker-Weber Theorem).
One of the goals of this course will be to prove Artin's reciprocity law, which relates abelian extensions to generalized ideal class groups. Artin's reciprocity law can be viewed as a sophisticated generalization of Gauss' quadratic reciprocity law. From the analytic point of view, Artin's reciprocity law states that L-functions associated to one-dimensional representations of abelian Galois groups are identical to Hecke L-series. This is the starting point (i.e. the "easy" case) of a far-reaching theory called the Langlands Program.

What is the essence of the similarity between forests in a graph and linearly independent sets of columns in a matrix? Why does the greedy algorithm produce a spanning tree of minimum weight in a connected graph? Can one test in polynomial time whether a matrix is totally unimodular? Matroid theory examines and answers questions like these.
This course will provide a comprehensive introduction to the basic theory of matroids.

A skein module of a 3-manifold is a module generated by the set of isotopy classes of links in the 3-manifold subject to certain linear relations specified by geometric modifications. Skein modules and related algebra may be used to construct link invariants and 3-manifold invariants. We will study the Jones polynomial and the Witten-Reshetikhin-Turaev invariants of 3-manifolds from the skein theory point of view.
