Quantum symmetry of graph C* -algebras

Abstract: Graph C*-algebras are examples of C*-algebras generated by partial isometries. The notion of quantum symmetry of graph C*-algebras will be discussed. Emphasis will be given on the invariance of KMS states of graph C*-algebras at critical inverse temperature under such quantum symmetry. The richness of quantum symmetry will be exhibited by a particular consideration. Also a unitary easy quantum group will be shown to appear as the quantum symmetry of a particular graph C*-algebra. The talk is based on a joint project with Arnab Mandal.
