## Noncommutative Geometry Seminar

**Date:** November 8, 2017

**Time:** 2:00PM - 2:50PM

**Location:** BLOC 628

**Speaker:** Rufus Willett, University of Hawaii

**Title:** *Finite dynamical complexity and controlled K-theory*

**Abstract:** I’ll discuss a notion of finite dynamical complexity introduced in joint work in Erik Guentner and Guoliang Yu. This notion applies for topological dynamical systems (and more generally for étale groupoids). I’ll sketch connections to amenability and the earlier idea of finite decomposition complexity (introduced by Guentner, Tessera, and Yu), and applications to computing K-theory.
