Relative position between a pair of spin model subfactors

KC Bakshi, S Guin - arXiv preprint arXiv:2212.07197, 2022 - arxiv.org
Jones proposed the study of two subfactors of a $ II_1 $ factor as a quantization of two
closed subspaces in a Hilbert space. The Pimsner-Popa probabilistic constant, Sano …

Quantum teleportation in the commuting operator framework

A Conlon, J Crann, DW Kribs, RH Levene - Annales Henri Poincaré, 2023 - Springer
We introduce a notion of teleportation scheme between subalgebras of semi-finite von
Neumann algebras in the commuting operator model of locality. Using techniques from …

Lattice of intermediate subalgebras

KC Bakshi, VP Gupta - Journal of the London Mathematical …, 2021 - Wiley Online Library
Analogous to subfactor theory, employing Watatani's notions of index and C∗‐basic
construction of certain inclusions of C∗‐algebras,(a) we develop a Fourier theory (consisting …

A few remarks on Pimsner–Popa bases and regular subfactors of depth 2

KC Bakshi, VP Gupta - Glasgow Mathematical Journal, 2022 - cambridge.org
We prove that a finite index regular inclusion of-factors with commutative first relative
commutant is always a crossed product subfactor with respect to a minimal action of a …

Regular inclusions of simple unital -algebras

KC Bakshi, VP Gupta - arXiv preprint arXiv:2404.06959, 2024 - arxiv.org
We prove that an inclusion $\mathcal {B}\subset\mathcal {A} $ of simple unital $ C^* $-
algebras with a finite-index conditional expectation is regular if and only if there exists a …

On Pimsner-Popa orthonormal basis and Popa's relative dimension of projections

KC Bakshi, S Guin - arXiv preprint arXiv:2311.13820, 2023 - arxiv.org
We show that any depth 2 subfactor with a simple first relative commutant has a unitary
orthonormal basis. As a pleasant consequence, we produce new elements in the set of …

Intermediate planar algebra revisited

KC Bakshi - International Journal of Mathematics, 2018 - World Scientific
In this paper, we explicitly work out the subfactor planar algebra P (N⊂ Q) for an
intermediate subfactor N⊂ Q⊂ M of an irreducible subfactor N⊂ M of finite index. We do …

On Intermediate Subfactors [HBNI Th127]

KC Bakshi - 2017 - imsc.res.in
In this thesis we examine Pimsner-Popa bases which are not necessarily orthonormal (as in
the book of Jones and Sunder) for an inclusion of subfactors of finite Jones' index and …
