On determining the domain of the adjoint operator

Functional Analysis 2011-06-13 v2 Spectral Theory

Abstract

A theorem that is of aid in computing the domain of the adjoint operator is provided. It may serve e.g. as a criterion for selfadjointness of a symmetric operator, for normality of a formally normal operator or for HH--selfadjointness of an HH--symmetric operator. Differential operators and operators given by an infinite matrix are considered as examples.
