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…
Angles Between Intermediate Operator Subalgebras
Ved Prakash Gupta, Deepika Sharma
Motivated by [2] and [5], the notions of interior and exterior angles between a pair of compatible intermediate W*-subalgebras of an inclusion of W*-algebras with a normal conditio…
Relations amongst the distances between -subalgebras and some canonically associated operator algebras
Ved Prakash Gupta, Sumit Kumar
We prove that the Christensen distance (resp., the Kadison-Kastler distance) between two -subalgebras and of a -algebra is equal…
Regular inclusions of simple unital -algebras
Keshab Chandra Bakshi, Ved Prakash Gupta
We prove that an inclusion of simple unital -algebras with a finite-index conditional expectation is regular if and only if there exists a fi…
