Weakly proper group actions, Mansfield's imprimitivity and twisted Landstad duality
Alcides Buss, Siegfried Echterhoff
Using the theory of weakly proper actions of locally compact groups recently developed by the authors, we give a unified proof of both reduced and maximal versions of Mansfield's I…
Imprimitivity theorems for weakly proper actions of locally compact groups
Alcides Buss, Siegfried Echterhoff
In a recent paper the authors introduced universal and exotic generalized fixed-point algebras for weakly proper group actions on C*-algebras. Here we extend the notion of weakly p…
Crossed products for actions of crossed modules on C*-algebras
Alcides Buss, Ralf Meyer
We decompose the crossed product functor for actions of crossed modules of locally compact groups on C*-algebras into more elementary constructions: taking crossed products by grou…
Universal and exotic generalized fixed-point algebras for weakly proper actions and duality
Alcides Buss, Siegfried Echterhoff
Given a C*-dynamical system (A,G,α), we say that A is a weakly proper (X\rtimes G)-algebra if there exists a proper G-space X together with a nondegenerate G-equivariant *-homomorp…
