Compressions of maximal dissipative and self-adjoint linear relations and of dilations Dedicated to Harm Bart - A fine colleague and good friend.

摘要

In this paper we generalize results from Stenger (1968) [30], Nudelman (2011) [28] and Azizov and Dijksma (2012) [7] to maximal dissipative and self-adjoint linear relations and discuss related results for nonnegative self-adjoint extensions of nonnegative symmetric linear relations and self-adjoint dilations of maximal dissipative linear relations.
