Vertically Integrated Research: Stochastic processes and partial differential equations. Prof. Fehrman
- Time: 1:30-2:20 MWF
- Instructor: Prof. Fehrman
- Prerequisite: Calculus (necessary), real analysis (preferred, but not necessary), probability (preferred, but not necessary)
- Text: The course will be based on notes provided by the professor. A good secondary reference is "Probability: Theory and Examples" by Rick Durrett (a free pdf copy is available on the author's website)
- Description: The purpose of this course is to develop the heuristic connections between random processes and partial differential equations on both theoretic and numerical levels. The course will begin with an overview of measure theoretic probability theory, including probability spaces, sigma algebras, filtrations, (Gaussian) random variables, and independence. The well-posedness of ordinary differential equations with Lipschitz continuous coefficients will then be established in order to motivate the study of discrete stochastic differential equations, which are, roughly speaking, ordinary differential equations perturbed by a random noise. Such equations model everything from the diffusion of aerosols in the wind, the advection of passive quantities like dye or energy in a fluid, and the evolution of a stock price. By developing a version of Ito's formula, which is the fundamental theorem of calculus for stochastic processes, we will show that the density of the solution to a stochastic differential equation can be described using the solution to a certain partial differential equation. This connection is known as the Feynman--Kac formula, and it will be the fundamental result of the course. We will then spend a significant amount of time applying this connection to model stochastic processes with connections to biology, physics, finance, and machine learning. In particular, we will derive the Black--Scholes equation, which is the most fundamental partial differential equations used to estimate European-style options in finance; discuss diffusion models in machine learning, which are a state-of-the-art technique for generating synthetic data, including images, in machine learning; and analyze stochastic gradient descent algorithms.

This is a self-contained introduction to modern probability theory. Starting from the concept of probability measures, it would introduce random variables, and independence. After a study of various modes of convergence, the Kolmogorov strong law of large numbers and results on random series will be established. Weak convergence of probability measures will be discussed in detail, which would lead to the central limit theorem and its applications. A main goal of the course is to develop the concept of conditional probability and its basic properties. Stochastic processes such as Brownian motion and martingales will be introduced, and their essential features, studied.

- Description: The evolution of many physical systems is fundamentally random. Even relatively simple processes, like random walks generated by a sequence of independent coin flips, can exhibit remarkably interesting behaviors, and such systems form the basis of our understanding of diverse phenomena in physics and biology and several of the computational techniques used in finance and machine learning. This course will focus, in particular, on stochastic processes in discrete time. We will develop the theory of discrete time martingales and Markov processes. Topics will include Doob's decomposition theorem, Doob's Martingale inequalities, the Burkholder-Davis-Gundy inequality, Kolmogorov's equations, generators, stationary measures, and some results in ergodic theory. We will also discuss some stochastic algorithms like Markov Chain Monte Carlo and diffusion models in machine learning. The course is provides the necessary background for Math 7366, which builds on Math 7365 to develop the theory of continuous-time martingales and Markov processes and and the theory of stochastic differential equations.

Seminar in Geometry and Algebraic Topology: Sigma-invariants of finitely generated groups. Prof. Dani
- Time: 10:30-11:20 MWF
- Instructor: Prof. Dani
- Prerequisite: MATH 7210 and 7512
- Text: Notes on the Sigma invariants by Ralph Strebel (available on arXiv)
- Description: The Sigma-invariants of a finitely generated group (also called BNSR-invariants) are an important tool in geometric group theory, with connections to many other topics, such as the Thurston norm and fibering of manifolds over S^1, Novikov homology, and resonance varieties. Defined in the 1980s by Bieri-Neuman-Strebel (in dimension 1) and Bieri-Renz (in higher dimensions), they are certain subsets of the character sphere of a group G, which encode a vast amount of information about the finiteness properties of subgroups of G. Recently, they have been successfully used in the study of interesting group theoretic questions such as virtual algebraic fibering and commensurability. Although they are rather hard to compute in general, they are now understood, at least in low dimensions, for various well-known classes of groups, such as generalized Baumslag-Solitar groups as well as many Artin and braid groups. In this course, we will begin with the geometric approach to the 1-dimensional Sigma invariants, following Strebel's "Notes on the Sigma invariants". Following that, we will explore further applications, explicit computations in specific classes of groups, and connections to other topics, to be determined by the interests of the class.

As project leaders, PhD students in the course should have Math 7210 and should have some knowledge of algebraic number theory.
- Text: Waldron, An Introduction to Finite Tight Frames
- Description: In this research-focused course, we will use computational tools to search for structures of interest to algebraic number theory, quantum information theory, and coding theory. These structures (called subspace packings, quantum designs, and/or fusion frames) are arrangements of subspaces in a finite-dimensional Hilbert space satisfying highly restrictive geometric constraints or symmetries. The prototypical examples are SIC-POVMs (symmetric, informationally complete positive operator-valued measures), or sets of d^2 complex equiangular lines in d-dimensional Hilbert space, whose conjectural classification ties them to deep number theory (class field theory for real quadratic fields). SIC-POVMs make up a small sliver of a vast space of potentially interesting subspace packings. The discovery of the number-theoretic features of SIC-POVMs was an accident made possibly by massive computer searches, and such searches are needed in other directions. Background on finite frame theory and connections to number theory will be provided through lectures, and students will pursue computational research projects in groups. Half of the in-class time will be spent in a computer lab.

Seminar in Geometry and Algebraic Topology: Rational Homotopy Theory. Prof. Bibby
- Time:

- Prerequisite: Strongly recommend some familiarity with homotopy theory (as in Math 7520 Algebraic Topology) and differential forms (as in Math 7550 Differential Geometry)
- Text: Rational Homotopy Theory and Differential Forms by Griffiths & Morgan (pdf available through LSU Library here)
- Description: The course will start with some basics of homotopy theory, fibrations, Postnikov towers, and de Rham cohomology. The goal is then to study the rational homotopy type of a simply-connected space X, which is the homotopy type of its localization (or rationalization). The homotopy and homology groups of the rationalization are rationalizations of those for X, killing all torsion. The rational homotopy type of X has the advantage of being more computable than the (ordinary) homotopy type of X, thanks to the algebraic models (using differential graded algebras or Lie algebras) from Sullivan and Quillen. The story is more complicated when X is not simply connected, when one needs to make sense of how to "rationalize" the (possibly non-abelian) fundamental group.
