Events for 01/24/2020 from all calendars

Probability Seminar

Time: 11:30AM - 12:30PM

Location: BLOC 628

Speaker: Pengfei Tang, Indiana Bloomington

Title: Weights of wired uniform spanning forests on nonunimodular transitive graphs

Abstract: Uniform spanning forests are interesting probability models that related to a lot of other areas of probability, including electrical networks, loop-erased random walk, the Abelian sandpile models. In this talk, we will focus on the geometry of wired uniform spanning forest on nonunimodular transitive graphs. In particular, we will show that almost surely every tree of the wired uniform spanning forests is light. More generally, tilted volumes for the trees in WUSF will be discussed.

Working Seminar on Quantum Computation and Quantum Information

Time: 1:30PM - 3:00PM

Location: BLOC 624

Speaker: Li Gao, TAMU

Title: A review of linear algebra for quantum computation

Abstract: We will do a quick review of the basics from linear algebra that are required for this semester's undergraduate research program.

Algebra and Combinatorics Seminar

Time: 3:00PM - 3:50PM

Location: BLOC 628

Speaker: Yuri Bahturin, Memorial University Newfoundland

Title: Group gradings and actions of pointed Hopf algebras

Abstract: Finite-dimensional pointed Hopf algebras with abelian groups of group-likes are generated by their group-like and skew primitive elements. This makes it possible to apply a well developed theory of group gradings on simple finite-dimensional associative algebras to the study of actions of a wide class of pointed Hopf algebras on these algebras. (joint work with Susan Montgomery)

Linear Analysis Seminar

Time: 4:00PM - 5:00PM

Location: BLOC 220

Speaker: Gilles Pisier, Texas A&M University

Title: Non-nuclear C*-algebras with WEP and LLP and the Connes-Kirchberg problem, part 2
