On the sum between a closable operator $T$ and a $T$ -bounded operator

Dan Popovici, Zoltán Sebestyén, Zsigmond Tarcsay

We provide several perturbation theorems regarding closable operators on a real or complex Hilbert space. In particular we extend some classical results due to Hess--Kato, Kato--Re…

On operators which are adjoint to each other

Dan Popovici, Zoltan Sebestyen

Given two linear operators $S$ and $T$ acting between Hilbert spaces $H$ and $K$ , respectively $K$ and $H$ which satisfy the relation \begin…
