The Fourier–Stieltjes algebra of a $C^*$-dynamical system II

Volume 256 / 2021

Erik Bédos, Roberto Conti Studia Mathematica 256 (2021), 217-239 MSC: Primary 46L55; Secondary 37A55, 43A35, 46H25. DOI: 10.4064/sm190826-25-3 Published online: 15 June 2020


We continue our study of the Fourier–Stieltjes algebra associated to a twisted (unital, discrete) $C^*$-dynamical system and discuss how the various notions of equivalence of such systems are reflected at the algebra level. As an application, we show that the amenability of a system, as defined in our previous work, is preserved under Morita equivalence.
