Forcing axioms and coronas of $C^*$-algebras

Logic 2021-06-17 v3 Operator Algebras

Abstract

We prove rigidity results for large classes of corona algebras, assuming the Proper Forcing Axiom. In particular, we prove that a conjecture of Coskey and Farah holds for all separable CC^*-algebras with the metric approximation property and an increasing approximate identity of projections.
