A Birman-Krein-Vishik-Grubb theory for sectorial operators

Christoph Fischbacher

We consider densely defined sectorial operators $A_{\pm}$ that can be written in the form $A_{\pm} = \pm i S + V$ with $D (A_{\pm}) = D (S) = D (V)$ , where both $S$ and…

The Non-Proper Dissipative Extensions of a Dual Pair

Christoph Fischbacher

We consider dissipative operators $A$ of the form $A = S + iV$ , where both $S$ and $V \geq 0$ are assumed to be symmetric but neither of them needs to be (essentially) selfadjoint. Afte…
