Linear Operators in Hilbert Spaces
Dmitri M Gitman, Igor Viktorovich Tyutin, Boris Leonidovich Voronov · Birkhäuser Boston eBooks · 2012
A solution of the problems raised in Introduction requires appealing to some nontrivial items of functional analysis concerning the theory of linear operators in Hilbert spaces, especially of unbounded symmetric and self-adjoint operators. We remind the reader of basic notions and facts from the theory of Hilbert spaces and of linear operators in such spaces which are relevant to the subject of the present book.
