Title: Central sequence algebras via nilpotent elements
Speaker: Tatiana Shulman (Chalmers)
Abstract:
A central sequence in a C*-algebra is a sequence (x_n) of elements such that [x_n, a] converges to zero, for any element a of the C*-algebra. In von Neumann algebra setting one typically means the convergence with respect to tracial norms, while in C*-theory it is with respect to the C*-norm. In this talk we will consider the C*-theory version of central sequences. We will discuss properties of central sequence algebras and in particular address a question of J. Phillips and of Ando and Kirchberg of which separable C*-algebras have abelian central sequence algebras.
Joint work with Dominic Enders.
