How is the Maximal Abelian Sub algebra look like in type II∞ von Neumann algebra up to unitary equivalence? I want kind of diagonal algebra sitting inside as MASA as my intuition says
This is a good question.
Here is a paper that explores MASA and von Neumann algebra:
A Correspondence between Maximal Abelian Sub-Algebras and Linear Logic Fragments
