Abstract The main results of the earlier chapter can be applied to those symmetric operators which are restrictions of self-adjoint operators. Therefore it is of interest to know which symmetric operators admit a self-adjoint extension. We shall now deal with this question. In this context let H be a complex Hilbert space.

In this chapter we consider quasi-self-adjoint extensions of, generally speaking, non-densely defined symmetric operators and establish analogues of von Neumann’s and \({\rm Krasnoselski\breve{i}^\prime s}\) formulas in cases of direct and indirect decompositions of their domains.

Self‐adjoint extensions for singular linear Hamiltonian systems
Mathematische Nachrichten, 2011AbstractThis paper is concerned with self‐adjoint extensions for singular linear Hamiltonian systems. The domain of the closure of the corresponding minimal Hamiltonian operator is described by the properties of its elements at the endpoints of the discussed interval, and two different decompositions of the domain of the corresponding maximal ...

Kreı̆n-Višik-Birman Self-Adjoint Extension Theory Revisited
2020The core results of the Krein-Visik-Birman theory of self-adjoint extensions of semi-bounded symmetric operators are reproduced, both in their original and in a more modern formulation, with a comprehensive discussion that includes missing details, elucidative steps, and intermediate results of independent interest.
