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…

On the Toeplitz algebras of right-angled and finite-type Artin groups
John Crisp, Marcelo Laca
The graph product of a family of groups lies somewhere between their direct and free products, with the graph determining which pairs of groups commute and which do not. We show th…
