Title: Exactness of locally compact groups.

Abstract:  Kirchberg and Wassermann introduced exactness for locally compact groups in order to study continuous bundles of C*-reduced crossed products. For a discrete group the exactness is equivalent to the topological amenability of the canonical action on its Stone–Čech compactification. In the talk, we will discuss their relation for general locally compact groups and answer a question raised by Anantharaman-Delaroche in 2002.
