Title: Minimal ambient nuclear C*-algebras

Time/Date: 4:45-6:15, Monday, June 6, 2016,

Room: 118

Abstract: Ambient nuclear C*-algebras play crucial roles in both von Neumann and C*-algebras. In this talk, we investigate how an ambient nuclear C*-algebra of a given C*-algebra can be "tight". For certain group C*-algebras, we construct ambient nuclear C*-algebras with no proper intermediate C*-algebras. This in particular gives the first examples of minimal ambient nuclear C*-algebras of non-nuclear C*-algebras. For this purpose, we study generic Cantor systems.
