Stuck in Traffic

Richard Sowers (Department of Mathematics, University of Illinois)

Abstract: Used Uber or Lyft lately? Been in a traffic jam lately? There is an increasing amount of interest and data in making 'cities' and 'mobility' smart. We take a look at some data and data reduction problems which we have been looking at for the past several months. We outline some current and new challenges. This is work with Professor Dan Work of Civil and Environmental Engineering, the PI4 program, and the IGL program.

Quasidiagonality of Nuclear C*-Algebras

Chris Linden (UIUC Math)

Abstract: Tikuisis, White, and Winter have shown that faithful traces on separable, nuclear C*-algebras which satisfy the UCT are quasidiagonal. As a corollary, the reduced group C*-algebra of an amenable group is quasidiagonal. I will discuss Schafhauser's recent proof of this theorem using the extension theory of C*-algebras.
