Abstract:

Given a twisted W*-dynamic system $(\M, \a, \s, G)$, let $\M\rtimes_{\a, \s}G$ be the associated twisted crossed product. In this talk, we first consider permanent properties under twisted crossed product like injectivity and w*-amenability. The second part of the talk is devoted to the study of Fourier multipliers on $\M\rtimes_{\a, \s}G$. We give criteria of completely bounded $L_p$ Fourier multipliers and establish a link between Fourier and Schur multipliers. This talk is based on a joint work with Xiao Xiong and Kai Zeng.
