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…

Intersection of conjugate Hadamard subfactors arising from Fourier matrices
Keshab Chandra Bakshi, Satyajit Guin, Guruprasad
Given two distinct complex Hadamard matrices belonging to the same equivalence class generated by the tensor products of Fourier matrices, we show that if the corresponding Hadamar…

Conjugate pairs of Hadamard subfactors and vertex models
Keshab Chandra Bakshi, Satyajit Guin, Guruprasad
We show that any two Hadamard subfactors arising from a pair of distinct complex Hadamard matrices of order 3 are either equal or conjugate by a unitary in the relative commutant o…
