Quantum Automorphism Group of Direct Sum of Cuntz Algebras
Ujjal Karmakar, Arnab Mandal
In this article, we explore the quantum symmetry of the direct sum of a finite family of Cuntz algebras , viewing them as graph -algebras ass…
Some Results on Bichon's Quantum Automorphism Group of Graphs
Rajibul Haque, Ujjal Karmakar, Arnab Mandal
The notion of the quantum automorphism group of a graph was introduced by J. Bichon in 2003 and T. Banica in 2005 respectively. This article explores primarily the quantum automorp…
Quantum Symmetries of Graph C*-algebras Having Maximal Permutational Symmetry
Ujjal Karmakar, Arnab Mandal
Quantum symmetry of a graph -algebra corresponding to a finite graph has been explored by several mathematicians within different categories in the past few…
Rigidity on Quantum Symmetry for a Certain Class of Graph C*-algebras
Ujjal Karmakar, Arnab Mandal
Quantum symmetry of graph -algebras has been studied, under the consideration of different formulations, in the past few years. It is already known that the compact quantum…
