Traceless AF embeddings and unsuspended $E$-theory

Abstract

I show that quasidiagonality and AF embeddability are equivalent properties for traceless C\mathrm C^\ast-algebras and are characterised in terms of the primitive ideal space. For nuclear C\mathrm C^\ast-algebras the same characterisation determines when Connes and Higson's EE-theory can be unsuspended.
