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.…

Unitary orthonormal bases of finite dimensional inclusions

Keshab Chandra Bakshi, B V Rajarama Bhat

We study unitary orthonormal bases in the sense of Pimsner and Popa for inclusions where are finite dimensional…

Commuting squares and planar subalgebras

Keshab Chandra Bakshi, Vijay Kodiyalam

We show a close relationship between non-degenerate smooth commuting squares of -factors with all inclusions of finite index and inclusions of subfactor planar algebras by sh…
