Title: [Colloquium] Comparison radius and mean dimension

Abstract: Comparison radius of a C*-algebra was introduced by Toms to measure the regularity of a C*-algebra, and it can be regarded as a C*-version of dimension growth. Mean topological dimension was introduced by Gromov and developed by Lindenstrauss and Weiss, and it is an invariant for topological dynamical systems which measures dimension growth along orbits. In the talk, I will discuss some estimations of the comparison radius of the crossed product C*-algebra in terms of the mean dimension of the dynamical system.
