Hecke algebras of semidirect products and the finite part of the Connes-Marcolli C*-algebra
Marcelo Laca, Nadia S. Larsen, Sergey Neshveyev
We study a C*-dynamical system arising from the ring inclusion of the 2\times 2 integer matrices in the rational ones. The orientation preserving affine groups of these rings form…

Phase transition in the Connes-Marcolli GL2-system
Marcelo Laca, Nadia Larsen, Sergey Neshveyev
We develop a general framework for analyzing KMS-states on C*-algebras arising from actions of Hecke pairs. We then specialize to the system recently introduced by Connes and Marco…

Boundary quotients and ideals of Toeplitz C*-algebras of Artin groups
John Crisp, Marcelo Laca
We study the quotients of the Toeplitz C*-algebra of a quasi-lattice ordered group (G,P), which we view as crossed products by a partial actions of G on closed invariant subsets of…
