Supercritical phase transition on the Toeplitz algebra of
Marcelo Laca, Tyler Schulz
We study the high-temperature equilibrium for the C*-algebra recently considered by an Huef, Laca and Raeburn. We show that the si…

Crystallization of C*-algebras
Marcelo Laca, Sergey Neshveyev, Makoto Yamashita
Given a C-algebra with an almost periodic time evolution , we define a new C-algebra , which we call the crystal of , that represents the zero temperat…

Relative topological principality and the ideal intersection property for groupoid C*-algebras
Chris J. Eagle, Gavin Goerke, Marcelo Laca
We introduce the notion of relative topological principality for a family of open subgroupoids of a Hausdorff étale groupoid . The C*-algebras of the g…
