Orthogonal unitary bases and a subfactor conjecture

J Crann, D Kribs, R Pereira - Proceedings of the American Mathematical …, 2023 - ams.org
We show that any finite dimensional von Neumann algebra admits an orthonormal unitary
basis with respect to its standard trace. We also show that a finite dimensional von Neumann …

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 …

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 …

[引用][C] A Family of Subfactors Arising from a pair of Complex Hadamard Matrices

KC Bakshi, S Guin - International Journal of Mathematics, 2024 - World Scientific
We define a new equivalence relation '∼'on the set of all Hadamard inequivalent complex
Hadamard matrices of order 4 and show that pairs (u, v) of equivalent matrices u∼ v …
