Weakly tracially approximately representable actions
M. Ali Asadi-Vasfi
Abstract:We describe a weak tracial analog of approximate representability under the name "weak tracial approximate representability" for finite group actions. We then investigate the dual actions on the crossed products by this class of group actions. Namely, let G be a finite abelian group, let A be an infinite-dimensional simple unital C*-algebra, and let α : G → Aut(A) be an action of G on A which is pointwise outer. Then α has the weak tracial Rokhlin property if and only if the dual action α of the Pontryagin dua… Show more
