On modular invariants of twisted group von Neumann algebras of almost unimodular groups

Aldo Garcia Guinto, Yuki Miyamoto

Given a locally compact second countable group $G$ with a 2-cocycle $\ddot{I}‰$, we show that the restriction of the twisted Plancherel weight $\ddot{I}{†}^{\ddot{I}}{‰}_G$ to the subalgebra generated by a c…
