$Z$ -stability for $C^{*}$ -algebras of minimal line-bundle-twisted homeomorphisms with the small boundary property

Marzieh Forough, Ja A Jeong, Karen R. Strung

In this paper we show that the Cuntz--Pimsner algebras associated to minimal homeomorphisms twisted by line bundles, along with their orbit-breaking subalgebras, are $Z$ -…

Recursive subhomogeneity of orbit-breaking subalgebras of $C^{*}$ -algebras associated to minimal homeomorphisms twisted by line bundles

Marzieh Forough, Ja A Jeong, Karen R. Strung

In this paper, we construct a recursive subhomogeneous decomposition for the Cuntz--Pimsner algebras obtained from breaking the orbit of a minimal Hilbert $C (X)$ -bimodule at a subs…

Quasi-invariant lifts of completely positive maps for groupoid actions

Suvrajit Bhattacharjee, Marzieh Forough

Let $G$ be a locally compact, Hausdorff, second countable groupoid and $A$ be a separable, $C_{0} (G^{(0)})$ -nuclear, $G$ - $C^{*}$ -algebra. We prove the existence of quasi-invariant, com…

$C^{*}$ -algebras associated to homeomorphisms twisted by vector bundles over finite dimensional spaces

Maria Stella Adamo, Dawn E. Archey, Marzieh Forough +4

In this paper we study Cuntz--Pimsner algebras associated to $C^{*}$ -correspondences over commutative $C^{*}$ -algebras from the point of view of the $C^{*}$ -al…

Equivariant bundles and absorption

Marzieh Forough, Eusebio Gardella

For a locally compact group $G$ and a strongly self-absorbing $G$ -algebra $(D, δ)$ , we obtain a new characterization of absorption of a strongly self-absorbing action usin…

Asymptotic lifting for completely positive maps

Marzieh Forough, Eusebio Gardella, Klaus Thomsen

Let $A$ and $B$ be $C^{*}$ -algebras with $A$ separable, let $I$ be an ideal in $B$ , and let $ψ : A \to B / I$ be a completely positive contractive linear map. We show that there is…

The Cuntz-Toeplitz algebras have nuclear dimension one

Philip Easo, Esperanza Garijo, Sarunas Kaubrys +12

We prove that unital extensions of Kirchberg algebras by separable stable AF algebras have nuclear dimension one. The title follows.

The weak tracial Rokhlin property for finite group actions on simple C*-algebras

Marzieh Forough, Nasser Golestani

We develop the concept of weak tracial Rokhlin property for finite group actions on simple (not necessarily unital) C*-algebras and study its properties systematically. In particul…

Stability of Fredholm property for regular operators on Hilbert $C^{*}$ -modules

Marzieh Forough

We study the stability of Fredholm property for regular operators on Hilbert $C^{*}$ -modules under some certain perturbations. We treat this problem when perturbing operators are (re…

Quasidiagonal traces and crossed products

Marzieh Forough

Let $A$ be a simple, exact, separable, unital $C^{*}$ -algebra and let $α : G \to A u t (A)$ be an action of a finite group $G$ with the weak tracial Rokhlin property. We sho…

Hilbert C-bimodules of finite index and approximation properties of C-algebras

Marzieh Forough, Massoud Amini

Let $A$ and $B$ be arbitrary $C^{*}$ -algebras, we prove that the existence of a Hilbert $A$ - $B$ -bimodule of finite index ensures that the WEP, QWEP, and LLP along with other finite-d…

Moore-Penrose inverse of Gram operator on Hilbert C*-modules

M. S. Moslehian, K. Sharifi, M. Forough +1

Let $t$ be a regular operator between Hilbert $C^{*}$ -modules and $t^{†}$ be its Moore-Penrose inverse. We investigate the Moore-Penrose invertibility of the Gram operator $t^{*} t$ . More…
