Addendum. On deformations of C*-algebras by actions of Kahlerian Lie groups

Abstract

We show that two approaches to equivariant deformation of C∗-algebras by actions of negatively curved K¨ahlerian Lie groups, one based on oscillatory integrals and the other on quantizations maps defined by dual 2-cocycles, are still equivalent despite the nonunitarity of our 2-cocycles.
