Winter 2021 Schedule
- January 8, 2021 Eloísa Grifo (UCR) Using computer software for commutative algebra research Abstract: Computer (algebra) software plays a very important role in modern mathematics research, and in particular in commutative algebra. We will talk briefly about why and how such software can be used in research, and introduce Macaulay2. We will see Macaulay2 in action, and give an overview of where and how one could learn more about using it.
- January 15, 2021 Branden Stone (Assured Information Security, Inc) Life as a government contractor Abstract: Before leaving academia I was always intrigued at what life would be like in industry. It turns out, it’s pretty fun! In this talk I will answer questions that I wish I knew as a graduate student. E.g. What is my day like? What type of problems do you work on? Is it selling out to work on government contracts? What could a commutative algebraist do? The answer may surprise you.

Jan 15th: Xiaolong Li, McMaster University
Moduli of continuity, gradient estimates and lower bounds of the first eigenvalue.
Abstract:In this talk, I will discuss the modulus of continuity estimates for quasilinear and fully nonlinear parabolic equations: the moduli of continuity of solutions to parabolic equations are subsolutions of suitable equations of one space variable. Then I will discuss two main applications: share time-interior gradient estimates and lower bounds of the first nonzero eigenvalue of the Laplacian on manifolds. The talk is based on several works, some of which are joint work with Dr. Kui Wang.

Harmonic branched coverings and uniformization of CAT($k$) spheres
Abstract:Consider a metric space $(S,d)$ with an upper curvature bound in the sense of Alexandrov (i.e.~via triangle comparison). We show that if $(S,d)$ is homeomorphically equivalent to the 2-sphere $\Sp^2$, then it is conformally equivalent to $\Sp^2$. The method of proof is through harmonic maps, and we show that the conformal equivalence is achieved by an almost conformal harmonic map. The proof relies on the analysis of the local behavior of harmonic maps between surfaces, and the key step is to show that an almost conformal harmonic map from a compact surface onto a surface with an upper curvature bound is a branched covering. This work is joint with Chikako Mese.

Lie Theory
This is the (minimal) website for the Lie Theory Seminar at UCR for the Winter 2021 quarter, which is organized by Vyjayanthi Chari.(The W2020 and F2020 schedules are below for posterity.)
The graduate students organize a Lie Theory Seminar for graduate students, as an extension of the Lie Theory Seminar to give talks on different areas in Representation Theory. The website is here.

January 26: Deniz Kus
Titles and Abstracts:
January 26: Prime representations in the HL category (by Denis Kuz)
Abstract: Generators and relations of graded limits of certain finite dimensional irreducible representations of quantum affine algebras have been determined in recent years. For example, the representations in the Hernandez-Leclerc category corresponding to cluster variables appear to be certain truncations of representations for current algebras and tensor products are related to the notion of fusion products. In this talk we will discuss some known results on this topic and study the classical characters of prime representations in the HL category.

Francesco Lin (Columbia) Title: Floer homology and closed geodesics of hyperbolic three-manifolds
Abstract: Floer homology and hyperbolic geometry are fundamental tools in the study of three-dimensional topology. Despite this, it remains an outstanding problem to understand whether there is any relationship between them. I will discuss some results in this direction that use as stepping stone the spectral geometry of coexact 1-forms. This is joint work with M. Lipnowski.
