A Complete Characterization of Regular Inclusions of Finite Dimensional -algebras
Keshab Chandra Bakshi, Indrajit Ghosh, Sumit Kumar
We give a complete characterization of regular (in the sense of Kumjian and Renault) unital inclusions of finite-dimensional -algebras. For subalgebras $\bigoplus_j( \mathbb{M…
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…
Unitary normalizers in finite-dimensional inclusions
Keshab Chandra Bakshi, Silambarasan C
We study regular inclusions of finite-dimensional von Neumann algebras from a matrix-theoretic perspective. To this end, we introduce a new combinatorial invariant of an inclusion,…
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…
A noncommutative construction of families of biunitary matrices and application to subfactors
Keshab Chandra Bakshi, Satyajit Guin, Guruprasad
We introduce a construction that, given a pair (u,v) of complex Hadamard matrices of the same order, generates infinitely many biunitary matrices of varying (and distinct) orders.…
