On quantum symmetries of graphs

Olha Ostrovska, Vasyl Ostrovskyi, Lyudmila Turowska

Let $G$ be a simple finite graph, and let $U_{G}$ be the related quantum graph. We study the game algebra $C (Qut (U_{G}))$ of quantum automorphism of $\mathca…

A class of representations of $C^{*}$ -algebra generated by $q_{ij}$ -commuting isometries

Olha Ostrovska, Vasyl Ostrovskyi, Danylo Proskurin +1

For $C^{*}$ -algebra generated by a finite family of isometries $s_{j}$ , $j = 1, \dots, d$ satisfying $q_{ij}$ -commutation relations \[ s_j^* s_j = I, \quad s_j^* s_k = q_{ij}s_ks_j^*, \qqu…
