Title: Almost ideal structures and K-theory
Abstract: The most basic (and powerful) tools to compute C*-algebra K-theory are probably the long-exact sequences associated to ideals. Unfortunately, many of the most interesting C*-algebras are simple, so these tools are inapplicable. I’ll discuss techniques to compute K-theory that work when one only has ‘approximate ideals’, examples coming from dynamics including simple C*-algebras, and applications to the Baum-Connes conjecture and Künneth formula.
