Compressions of maximal dissipative and self-adjoint linear relations and of dilations

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.
