Description

The idea of the talk is to bring together the well known Blaschke product and operator algebras. We suggest the notion of the Blaschke $C^*$-algebra, which is the universal $C^*$-algebra generated by some relations. The relations are defined by a family of finite Blaschke products. In this way we extend the Coburn’s Theorem for a family of non-unitary isometries connected by a family of finite Blaschke products. We show that the Blaschke $C^*$-algebras is isomorphic to the inductive limit of Toeplitz algebras.
The talk is based on the joint work with Tamara Grigoryan.
