Extension of automorphisms to C*-crossed products with non-trivial centre
Roberto Conti, Ezio Vasselli
Given a quasi-special endomorphism of a C*-algebra A with nontrivial center, we study an extension problem for automorphisms of A to a minimal cross-product B of A by . Expl…

Gauge-equivariant Hilbert bimodules and crossed products by endomorphisms
Ezio Vasselli
C*-endomorphisms arising from superselection structures with non-trivial centre define a 'rank' and a 'first Chern class'. Crossed products by such endomorphisms involve the Cuntz-…

Realization of minimal C*-dynamical systems in terms of Cuntz-Pimsner algebras
Fernando Lledó, Ezio Vasselli
In the present paper we study tensor C*-categories with non-simple unit realised as C*-dynamical systems (F,G,β) with a compact (non-Abelian) group G and fixed point algebra A := F…
