Maximal amenable MASAs of the free group factor of two generators arising from the free products of hyperfinite factors
Koichi Shimada
In this paper, we give examples of maximal amenable subalgebras of the free group factor of two generators. More precisely, we consider two copies of the hyperfinite factor o…

Maximal amenability of the generator subalgebra in -Gaussian von Neumann algebras
Sandeepan Parekh, Koichi Shimada, Chenxu Wen
In this article, we give explicit examples of maximal amenable subalgebras of the -Gaussian algebras, namely, the generator subalgebra is maximal amenable inside the -Gaussia…
