Splitting of Tensor Products and Intermediate Factor Theorem: Continuous Version

Tattwamasi Amrutam, Yongle Jiang

Let $G$ be a discrete group. Given unital $G$ - $C^{*}$ -algebras $A$ and $B$ , we give an abstract condition under which every $G$ -subalgebra $C$ of the fo…

Crossed products of dynamical systems; rigidity Vs. strong proximality

Tattwamasi Amrutam, Eli Glasner, Yair Glasner

Given a dynamical system $(X, Γ)$ , the corresponding crossed product $C^{*}$ -algebra $C (X) ⋊_{r} Γ$ is called reflecting, when every intermediate $C^{*}$ -algebra $C^*_r(Γ)<\mathcal…

On relative commutants of subalgebras in group and tracial crossed product von Neumann algebras

Tattwamasi Amrutam, Jacopo Bassi

Let $Γ$ be a discrete group acting on a compact Hausdorff space $X$ . Given $x \in X$ , and $μ \in Prob (X)$ , we introduce the notion of contraction of $μ$ towards $x$ with respec…
