Events for 02/15/2017 from all calendars
Noncommutative Geometry Seminar
Time: 2:00PM - 2:50PM
Location: BLOC 628
Speaker: Yeong Chyuan Chung, Texas A&M University
Title: Quantitative K-Theory and its Applications
Abstract: We will describe quantitative K-theory for C*-algebras and our work in extending the theory to more general Banach algebras, in particular to L^p operator algebras. We will also discuss how the use of quantitative K-theory facilitates computation of the (ordinary) K-theory of L^p crossed products under the assumption of finite dynamic asymptotic dimension.
Groups and Dynamics Seminar
Time: 3:00PM - 4:00PM
Location: BLOC 220
Speaker: Volodymyr Nekrashevych
Title: Topological full groups of minimal Z^d actions
Abstract: I will discuss algebraic properties of topological full groups of minimal Z^d actions on the Cantor set: simplicity, generating sets. Some examples will be described: groups of interval exchange transformations, the full group of the Penrose tiling. This is a joint work with Kate Juschenko and Maxym Chornyi.
Student Working Seminar in Groups and Dynamics
Time: 4:00PM - 5:00PM
Location: BLOC 628
Speaker: Krzysztof Święcicki, Texas A&M University
Title: Group without weak expanders and no coarse embedding into Hilbert space
