Regular diagonal subfactors
Keshab Chandra Bakshi, Ved Prakash Gupta, Guruprasad +1
We show that a diagonal subfactor arising from a finite family of automorphisms of a -factor is regular precisely when the classes of the defining automorphisms occur wit…

Weak quantum hypergroups from finite index C*-inclusions
Keshab Chandra Bakshi, Debashish Goswami, Biplab Pal
We study a finite index inclusion of simple unital C*-algebras and construct a canonical completely positive coproduct on the second relative commutant, thereby endowing it with a…

Higher reflections and entropy of canonical shifts for inclusions of -algebras with finite Watatani index
Keshab Chandra Bakshi, Satyajit Guin, Biplab Pal +1
Given a unital inclusion of simple -algebras equipped with a conditional expectation of index-finite type, we study Fourier transforms and rotation operators and introduce the…
