Using entropy to compute phase transitions for Pimsner algebras

Evgenios Kakariadis (Newcastle University)

Thursday 7th March, 2019 16:00-17:00 Maths 311B


KMS-states of Pimsner algebras have been under thorough study in the past years. Their phase transitions can give an invariant for gauge-preserving isomorphisms. In this talk I will present how the notion of entropy mixes with their parametrization and recovers past results. Time permitted we will discuss how this works for graph algebras and Nica-Pimsner algebras.
