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…

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.…
