Kadison-Kastler Distance and Interior Angle for Masas: Connections with Entropy and Probabilistic Index

Indrajit Ghosh, Sumit Kumar

We study the Kadison--Kastler distance and the interior angle between masas in finite-dimensional matrix algebras. In \(\mathbb{M}_2(\mathbb{C})\), we obtain an explicit formula fo…
