Non-Commutative Geometry Seminar

Abstract: Recent remarkable work by several researchers in the classification theory of simple separable nuclear C*-algebras has boiled down the problem of classifying the crossed products of free minimal actions of amenable groups to the single question of whether the nuclear dimension is finite. I will discuss different strategies for verifying finite nuclear dimension dynamically, with a focus on actions on the Cantor set and the connection to recent tiling results for amenable groups
