Research Training Seminar
Early graduate students (as well as advanced undergraduates), are encouraged to participate in annual RTG training seminars.
These annual seminars will have students work through research material in a collaborative setting, leading towards producing research in or
a new exposition of a research topic.
Current topic: (run by Karl Schwede): During the Fall semester we will learn about Macaulay2 (an open source computer algebra system for commutative algebra and algebraic geometry https://www.macaulay2.com/). We will take turns presenting on mathematical aspects of Macaulay2. Later in Fall, and into spring, we will break into groups and write packages for Macaulay2, as well as papers to be submitted to JSAG, a refereed journal.
The website for the seminar is here: https://www.math.utah.edu/~schwede/M2RTG/
Previous topic: (run by Kurt Vinhage): During the Fall semester 2023 we will review some fundamental definitions about entropy of probability measure preserving dynamical systems, including generalizations which can be adapted to low complexity systems or group actions. We will aim to understand two recent developments: values and properties for unipotent flows and group actions (due to Kanigowski, Kunde, Vinhage and Wei), as well as for smooth abelian hyperbolic group actions (due to Katok, Katok and Rodriguez Hertz).
Students will be asked to read and present aspects of the survey paper of Kangiowski, Katok and Wei (available here: https://arxiv.org/pdf/2004.04655.pdf). Other resources will be provided as necessary. During the spring semester, we will focus on computing the Fried average entropy of some systems, and investigating how these change under (smooth) time changes.

- Sean Howe: Sean works at the crossroads of algebraic geometry, number theory, and representation theory. His current research focuses on: 1) p-adic automorphic forms and their role in the p-adic Langlands program, and 2) arithmetic and motivic statistics. Most of his work is on problems that connect representation theoretic structures to the geometry and topology of moduli spaces.
