Voiculescu's Theorem for Nonseparable C*-algebras

Logic 2018-11-29 v2 Operator Algebras

Abstract

We prove that Voiculescu's noncommutative version of the Weyl-von Neumann theorem can be extended to all (not necessarily separable) unital, separably representable C*-algebras whose density character is strictly smaller than p\mathfrak{p}. We show moreover that Voiculescu's theorem consistently does not generalize to C*-algebras of larger density character.
