Title: Subshifts, perforation, and classification
Abstract: In 1998, Villadsen exhibited a simple C*-algebra with perforated K0-group. His construction, which lies within the class of AH-algebras, has considerably impacted Elliott's classification program. We will explain how to recast Villadsen's ideas in a dynamical framework to obtain a simple crossed product C*-algebra with perforation. This is joint work with David Kerr.
