SUMMARY:KK-rigidity of simple nuclear C*-algebras - Christopher  Schafhaus

DESCRIPTION:A landmark result in C*-algebra theory is the classification o
 f unital separable simple nuclear Z-stable C*-algebras satisfying the univ
 ersal coefficient theorem (UCT) in terms of their K-theory and traces. I w
 ill discuss this result with a focus on the role of UCT. &nbsp\;In the inf
 inite setting\, without the UCT\, two unital Kirchberg algebras are isomor
 phic if and only they are KK-equivalent in a unit-preserving way. I&rsquo\
 ;ll discuss some results along these lines in the finite case.
