Crossed products and entropy of automorphisms
Ciprian Pop, Roger R. Smith
Let A be an exact C^*-algebra, let G be a locally compact group, and let (A,G,α) be a C*-dynamical system. Each automorphism α_g induces a spatial automorphism Ad_{\lamba_g} on the…

Finite sums of commutators
Ciprian Pop
We show that elements of unital -algebras without tracial states are finite sums of commutators. Moreover, the number of commutators involved is bounded, depending only on the…

Representable bimodules over C*-algebras
C. Pop
Given two C*-algebras A and B, abstract A-B bimodules that can be isometrically represented as operator bimodules are characterised in terms of their norm. Various properties of su…
