Regular diagonal subfactors
Keshab Chandra Bakshi, Ved Prakash Gupta, Guruprasad +1
The paper characterizes when a diagonal subfactor of a II₁ factor is regular, showing this occurs exactly when the defining automorphisms form a subgroup of the outer automorphism…
Regular irreducible inclusions of simple -algebras and crossed product structure
Keshab Chandra Bakshi, Silambarasan C, Biplab Pal
We study regular irreducible inclusions of simple unital -algebras admitting a conditional expectation. We introduce a generalized notion of quasi-basis extending…
Depth 2 inclusions of simple -algebras and their weak -Hopf algebra symmetries
Biplab Pal
Let be a depth inclusion of simple unital -algebras with a conditional expectation of index-finite type. We show that the second relative commutant $B' \cap…
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…
