Abstract
The operator and the block-operator matrix forms for extremal rigid and soft extensions of a C(α)-suboperator in a Hilbert space are given. Representations of the Friedrichs and Krein-von Neumann maximal sectorial extensions of a sectorial linear relation space as strong resolvent limits of a family maximal accretive extensions are obtained.
