Operator Michelson Contrast: Logarithmic Parametrisation, Subadditivity, and a Sharp Noncommutativity Threshold
Irina Nikolaeva, Andrej Novikov
We study the operator Michelson contrast Delta(A) = (kappa(A)-1)/(kappa(A)+1), with kappa(A)=||A|| ||A^{-1}||, for positive invertible operators, and introduce its logarithmic para…

Finite-Dimensional Type I von Neumann Algebras in PyTorch: A GPU-Accelerated Framework for Random Block-Diagonal Operators
Irina Nikolaeva, Andrej Novikov
We present \texttt{torch\_vn\_algebra}, an open-source Python library built on PyTorch for numerical experiments with finite-dimensional Type I von Neumann algebras (direct sums of…

Generalisation of Michelson contrast for operators and its properties
Sami Abdullah Abed, Irina Nikolaeva, Andrei Novikov
In this article we consider generalisation of Michelson contrast for positive operators of countably decomposable -algebras and find a few several of its properties.
