Full factors, bicentralizer flow and approximately inner automorphisms

Amine Marrakchi

We show that a factor $M$ is full if and only if the $C^{*}$ -algebra generated by its left and right regular representations contains the compact operators. We prove that the bicentr…

Fullness of crossed products of factors by discrete groups

Amine Marrakchi

Let $M$ be an arbitrary factor and $σ : Γ ↷ M$ an action of a discrete group. In this paper, we study the fullness of the crossed product $M ⋊_{σ} Γ$ . When $Γ$ is a…
