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…

On orthogonal systems, two-sided bases and regular subfactors
Keshab Chandra Bakshi, Ved Prakash Gupta
We prove that a regular subfator of type with finite Jones index always admits a two-sided Pimsner-Popa basis. This is preceeded by a pragmatic revisit of Popa's notion of o…

A note on irreducible quadrilaterals of factors
Keshab Chandra Bakshi, Ved Prakash Gupta
Given any finite index quadrilateral of -factors, the notions of interior and exterior angles between and were introduced in \cite{BDLR2017}. We determ…
