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…

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…
