Prerequisites: Familiarity with basic group theory and linear algebra, such as from Math 4200 and Math 4153.
Text: Fulton, Young Tableaux, London Mathematical Society Student Texts No. 35, London Mathematical Society, 1996.
This semester will be about uses of easy combinatorial models to solve longstanding open questions in representation theory and topology. (It continues last semester's theme, but last semester is not a prerequisite.) The combinatorial models include honeycombs (certain planar graphs made up of hexagons) and the closely related hives, as well as puzzles (pictures in the plane made of equilateral triangles and rhombi). These models can be used to study the representation theory of GL(n,C) and the topology of Grassmannians (the space of k-planes in Cⁿ). One application of these methods is the solution of the Hermitian eigenvalue problem: If you know the eigenvalues of two Hermitian matrices A and B, what can you say about the possible eigenvalues of A+B?

In many applications data (of numerical information) can be represented by a point set in an n-dimensional space. Computational topology focuses on the computational aspects of topology, and applies topological tools to analysis of those data sets. Topological tools of simplicial homology, shape and discrete morse theory will be presented. Algorithms and software for the analysis of the topology, connectivity and shape of point sets will be explored. Projects will be either a software exploration implementation on a point data set of interest to you or a presentation of recent papers in the area.

In this course we provide an introduction to theory behind the design of metal-dielectric crystals 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 metamaterial crystals. 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 nobel metals. 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 necessary for designing structured media supporting backward waves and behavior associated with an effective negative index of refraction. We conclude by introducing multiscale techniques necessary for computing the effective dielectric properties of metamaterials and higher order corrections.

MATH 7520: Algebraic Topology.
12:00-1:20 T Th
Instructor: Prof. Cohen.
Prerequisites: 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, the homology groups) 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 previously. 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, or other elements of algebraic topology, such as homotopy theory.

MATH 7590: Chern-Simons Theory.
9:00-10:20 T Th
Instructor: Prof. Baldridge.
Prerequisites: Some differential forms and Lie groups knowledge is helpful
Text: Gauge Fields, Knots and Gravity by John Baez & Javier P. Muniain
How is knot theory related to theoretical physics? This course is a gentle introduction to the mathematical tools needed to understand the relationship between knot theory and Chern-Simons theory. First we will use differential forms to formulate Maxwell’s equations of electromagnetism. Then we introduce connections on vector bundles whose underlying structure group is from a list of certain Lie groups, and we use the connections and curvature to generalize Maxwell theory to the Yang-Mills equations. This in turn motivates Chern-Simons theory and its relationship to knot theory.

10:30-11:50 T Th
Instructor: Profs. Achar and Sage
Prerequisites: Familiarity with basic group theory and linear algebra, such as from Math 4200 and Math 4153.
Text: . Fulton, Young Tableaux, London Mathematical Society Student Texts No. 35, London Mathematical Society, 1996.
This semester will be about uses of easy combinatorial models to solve longstanding open questions in representation theory and topology. (It continues the theme of the last two semesters, but those semesters are not prerequisites for this course.) The combinatorial models include honeycombs (certain planar graphs made up of hexagons) and the closely related hives, as well as puzzles (pictures in the plane made of equilateral triangles and rhombi). These models can be used to study the representation theory of GL(n,C) and the topology of Grassmannians (the space of k-planes in Cⁿ). One application of these methods is the solution of the Hermitian eigenvalue problem: If you know the eigenvalues of two Hermitian matrices A and B, what can you say about the possible eigenvalues of A+B?

Prerequisites: Math 7211 or permission of the instructor
Text: Lectures on differential Galois Theory by Andy Magid, AMS University Lecture Series, Volume 7 (1994) ISBN-10: 0-8218-7004-1 ISBN-13: 978-0-8218-7004-4
In the same way that Galois theory has its origins in studying the symmetries of the solutions of a polynomial, differential Galois theory grew out of the analogous problem for linear differential equations. More precisely, differential Galois theory studies extensions of differential fields, i.e., fields equipped with a derivation (a map obeying the Leibnitz rule). As the name suggests, there is a remarkable formal parallelism between the two theories. In particular, there is a fundamental theorem of differential Galois theory. Indeed, for appropriate differential field extensions E/F, the differential automorphisms fixing F forms a group called the differential Galois group G, and there is a one-to-one inclusion reversing correspondence between closed subgroups of G and intermediate differential field extensions. However, whereas classical Galois groups are finite (or at worst profinite), differential Galois groups are linear algebraic groups.
This class will provide an introduction to differential Galois theory. We will discuss Picard-Vessiot extensions (the differential analogue of Galois extensions) and give several different constructions of the differential Galois group. We will prove the fundamental theorem and consider when differential equations are solvable by quadratures—the differential analogue of solvability by radicals. We will further discuss the monodromy group of linear differential equations and its relationship to the differential Galois group.

Text: Matroid Applications edited by Neil White (Chapter 6: The Tutte Polynomial and its Applications by Thomas Brylawski and James Oxley)
The theory of numerical invariants for matroids is one of many aspects of matroid theory having its origins within graph theory. Most of the fundamental ideas in matroid invariant theory were developed from graphs by Veblen, Birkhoff, Whitney, and Tutte when considering colorings and flows in graphs. This course will introduce the Tutte polynomial for matroids and will consider its applications in graph theory, coding theory, percolation theory, electrical network theory, and statistical mechanics.

We will discuss the homology groups of topological spaces. To a topological space, one associates a sequence of abelian groups called their homology groups. To a continuous map, one associates a sequence of group homomorphisms in a functorial way. One application of homology is the Brouwer fixed point theorem which asserts any continuous map from an n-dimensional disk to itself has a fixed point. One also has a higher dimensional version of the Jordan curve theorem. We will learn to calculate homology groups in a variety of ways. If time permits, we will begin to discuss cohomology as well.

Prerequisites: Math 7510 and prior completion of or concurrent enrollment in Math 7512
Text: A primer on Mapping Class Groups by Benson Farb and Dan Margalit, Princeton University Press, 2011.
The mapping class group of a surface is the group of its orientation preserving homeomorphisms (up to a certain equivalence relation). The study of mapping class groups is a classical subject which has exploded in the last decade.
In this course we will study the algebraic structure of mapping class groups and the detailed description of its individual elements. This includes the Nielsen – Thurston classification theorem, which gives a particularly nice representative for each element of the group. Furthermore, we will introduce spaces on which mapping class groups act, such as the complex of curves and Teichmüller space. An important theme throughout the course will be the relationships between the geometry of these spaces, the algebra of the mapping class group, and the topology of the surface.

9:00-10:20 T Th
Instructor: Prof. Vela-Vick.

Beginning with some basic examples and constructions, we will eventually move on to the problem of classifying vector bundles. Along the way, we will construct Stiefel-Whitney, Euler, Chern and Pontryagin classes.
