Quantum symmetries of the twisted tensor products of C*-algebras
Jyotishman Bhowmick, Arnab Mandal, Sutanu Roy +1
We consider the construction of twisted tensor products in the category of C*-algebras equipped with orthogonal filtrations and under certain assumptions on the form of the twist c…
Compact quantum metric spaces from quantum groups of rapid decay
Jyotishman Bhowmick, Christian Voigt, Joachim Zacharias
We present a modified version of the definition of property RD for discrete quantum groups given by Vergnioux in order to accommodate examples of non-unimodular quantum groups. Mor…
Quantum group of automorphisms of a finite quantum group
Jyotishman Bhowmick, Adam Skalski, Piotr M. Sołtan
A notion of a quantum automorphism group of a finite quantum group, generalising that of a classical automorphism group of a finite group, is proposed and a corresponding existence…
Deformation of operator algebras by Borel cocycles
Jyotishman Bhowmick, Sergey Neshveyev, Amandip Sangha
Assume that we are given a coaction δof a locally compact group G on a C*-algebra A and a T-valued Borel 2-cocycle ωon G. Motivated by the approach of Kasprzak to Rieffel's deforma…
Quantum isometry groups of noncommutative manifolds associated to group C*-algebras
Jyotishman Bhowmick, Adam Skalski
Let G be a finitely generated discrete group. The standard spectral triple on the group C*-algebra C*(G) is shown to admit the quantum group of orientation preserving isometries. T…
Some counterexamples in the theory of quantum isometry groups
Jyotishman Bhowmick, Debashish Goswami
By considering spectral triples on () constructed by Chakraborty and Pal (\cite{chak_pal}), we show that in general the quantum group of volume and orientation…
