The Connes-Kasparov conjecture for almost connected groups
Jerome Chabert, Siegfried Echterhoff, Ryszard Nest
Let be a locally compact group with cocompact connected component. We prove that the assembly map from the topological $\k$-theory of to the $\k$-theory of the reduced $C^*…

Full duality for coactions of discrete groups
Siegfried Echterhoff, John Quigg
Using the strong relation between coactions of a discrete group G on C*-algebras and Fell bundles over G, we prove a new version of Mansfield's imprimitivity theorem for coactions…

Maximal Coactions
Siegfried Echterhoff, S. Kaliszewski, John Quigg
A coaction d of a locally compact group G on a C*-algebra A is maximal if a certain natural map from A times_d G times_{d hat} G onto A otimes K(L^2(G)) is an isomorphism. All dual…
