Quantum edge correspondences and quantum Cuntz-Krieger algebras

Michael Brannan, Mitch Hamidi, Lara Ismert +2

Given a quantum graph , we define a C*-correspondence over the noncommutative vertex C*-algebra , called the quantum edge correspondence. Fo…

On the isomorphism class of -Gaussian C-algebras for infinite variables

Matthijs Borst, Martijn Caspers, Mario Klisse +1

For a real Hilbert space and Bozejko and Speicher introduced the C-algebra and von Neumann algebra

A simple proof of the complete metric approximation property for q-Gaussian algebras

Mateusz Wasilewski

The aim of this note is to give a simpler proof of a result of Avsec, which states that -Gaussian algebras have the complete metric approximation property.

-cohomology, derivations and quantum Markov semi-groups on -Gaussian algebras

Martijn Caspers, Yusuke Isono, Mateusz Wasilewski

We study (quasi-)cohomological properties through an analysis of quantum Markov semi-groups. We construct higher order Hochschild cocycles using gradient forms associated with a qu…

Bigalois extensions and the graph isomorphism game

Michael Brannan, Alexandru Chirvasitu, Kari Eifler +4

We study the graph isomorphism game that arises in quantum information theory from the perspective of bigalois extensions of compact quantum groups. We show that every algebraic qu…

Inversion problem in measure and Fourier-Stieltjes algebras

Przemysław Ohrysko, Mateusz Wasilewski

In this paper we study the inversion problem in measure and Fourier-Stieltjes algebras from qualitative and quantitative point of view extending the results obtained by N. Nikolski…
