# Events for 01/24/2020 from all calendars

## Probability Seminar

## Working Seminar on Quantum Computation and Quantum Information

## Algebra and Combinatorics Seminar

## Linear Analysis 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.

**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.

**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)

**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*
