Characterizations of type 1 subdiagonal algebras and an application
Let $\mathfrak A$ be a maximal subdiagonal algebra in a $\sigma$-finite von Neumann algebra $\mathcal M$ with respect to a faithful normal conditional expectation $\Phi$. We consider the characterizations for $\mathfrak A$ to be a type 1 subdiagonal algebra in the sense that every right invariant subspace in noncommutative $H^2$ …
