From endomorphisms to automorphisms and back: dilations and full corners

Marcelo Laca

When S is a discrete subsemigroup of a discrete group G such that G = S^{-1} S, it is possible to extend circle-valued multipliers from S to G; to dilate (projective) isometric rep…

The ideal structure of the Hecke C*-algebra of Bost and Connes

Marcelo Laca, Iain Raeburn

We compute explicitly the primitive ideal space of the Bost-Connes Hecke C*-algebra by embedding it as a full corner in a transformation group C*-algebra and applying a general the…
