The analogue of Choi matrices for a class of linear maps on Von Neumann algebras
Erling Stormer
TL;DR
This paper extends the concept of Choi matrices from finite-dimensional matrices to factors in von Neumann algebras, establishing foundational theorems in this broader setting.
Contribution
It generalizes Choi matrices to factors in von Neumann algebras and proves fundamental theorems in this new context.
Findings
Choi matrices are extended to factors in von Neumann algebras.
Basic theorems for Choi matrices are established in this setting.
Abstract
The definition of Choi matrices for linear maps on the n x n matrices is extended to factors, and the basic theorems for Choi matrices are proved in this general context.
