Planar algebras, quantum information theory and subfactors
Vijay Kodiyalam, Sruthymurali, V. S. Sunder
We define generalised notions of biunitary elements in planar algebras and show that objects arising in quantum information theory such as Hadamard matrices, quantum latin squares…
On a presentation of the spin planar algebra
Vijay Kodiyalam, Sohan Lal Saini, Sruthymurali +1
We define a certain abstract planar algebra by generators and relations, study various aspects of its structure, and then identify it with Jones' spin planar algebra.
The Functional Analysis of Quantum Information Theory
Ved Prakash Gupta, Prabha Mandayam, V. S. Sunder
This book is a compilation of notes from a two-week international workshop on the "The Functional Analysis of Quantum Information Theory" that was held at the Institute of Mathemat…
Extendable endomorphisms on factors
Panchugopal Bikram, Masaki Izumi, R. Srinivasan +1
We begin this note with a von Neumann algebraic version of the elementary but extremely useful fact about being able to extend inner-product preserving maps from a total set of the…
Continuous minimax theorems
Madhushree Basu, V. S. Sunder
In classical matrix theory, there exist useful extremal characterizations of eigenvalues and their sums for Hermitian matrices (due to Ky Fan, Courant-Fischer-Weyl and Wielandt) an…
Hilbert von Neumann modules
Panchugopal Bikram, Kunal Mukherjee, R. Srinivasan +1
We introduce a way of regarding Hilbert von Neumann modules as spaces of operators between Hilbert space, not unlike [Skei], but in an apparently much simpler manner and involving…
