Connes-embeddability and twisted group von Neumann algebras

Soham Chakraborty, Felipe Flores

We call a countable discrete group cocycle-hyperlinear if all its twisted group von Neumann algebras are Connes-embeddable. We show that the class of cocycle-hyperlinear groups inc…

Rapid decay and functional calculus in $C^{*}$ -probability spaces

Felipe Flores

Let $(A, ρ)$ be a tracial $C^{*}$ -probability space with the rapid decay property relative to a filtration $L$ . We show that the associated Sobolev algebra $H_{L}^{\infty} (A, ρ)$ i…

Simplicity and pure infiniteness for $C^{*}$ -algebras associated with stabilizers of boundary actions

Felipe Flores, Joseph Gondek

Given a discrete group $Γ$ acting on a compact space $X$ , and a stabilizer subgroup $Λ \leq Γ$ of $X$ , we use the Rieffel induction of covariant $(Λ, X)$ -representations to study cl…

Pureness and stable rank one for reduced twisted group $C^{*}$ -algebras of certain group extensions

Felipe Flores, Mario Klisse, Mícheál Ó Cobhthaigh +1

We present a sufficient condition for a (twisted) group action on a $C^{*}$ -algebra such that the corresponding reduced (twisted) group $C^{*}$ -algebra inclusio…

Selfless reduced free products and graph products of $C^{*}$ -algebras

Felipe Flores, Mario Klisse, Mícheál Ó Cobhthaigh +1

Under mild assumptions, we show that reduced free products and reduced graph products of $C^{*}$ -algebras are completely selfless, without assuming the rapid decay prop…

Discrete measured groupoid von Neumann algebras via the Gaussian deformation

Felipe Flores, James Harbour

Given a discrete measured groupoid $G$ , we study properties of the corresponding von Neumann algebra $L (G)$ using the techniques of Popa's deformation/rigidity…

On the topological ranks of Banach $^{*}$ -algebras associated with groups of subexponential growth

Felipe I. Flores

Let $G$ be a group of subexponential growth and $C \to q G$ a Fell bundle. We show that any Banach $^{*}$ -algebra that sits between the associated $ℓ^{1}$ -algebra…

Twisted convolution algebras with coefficients in a differential subalgebra

Felipe I. Flores

Let $(G, α, ω, B)$ be a measurable twisted action of the locally compact group $G$ on a Banach $^{*}$ -algebra $B$ and $A$ a differential Banac…

A criterion for hypersymmetry on discrete groupoids

F. Flores

Given a Fell bundle $C \to q Ξ$ over the discrete groupoid $Ξ$ , we study the symmetry of the associated Hahn algebra $ℓ^{\infty, 1} (Ξ ∣ C)$ in ter…

Symmetry for algebras associated to Fell bundles over groups and groupoids

Felipe Flores, Diego Jauré, Marius Mantoiu

To every Fell bundle $C$ over a locally compact group $G$ one associates a Banach $^{*}$ -algebra $L^{1} (G ∣ C)$ . We prove that it is symmetric whene…
