Strong $C^*$-rigidity of the Heisenberg groups

Representation Theory 2025-11-11 v2 Operator Algebras

Abstract

We prove a strong rigidity property of the Heisenberg groups, that is, they can be distinguished from any other 1-connected Lie groups via their unitary dual spaces, in particular via the Morita equivalence class of their group CC^*-algebras.
