Hilbert Space, Boundary Value Problems and Orthogonal Polynomials

This monograph consists of three parts: - the abstract theory of Hilbert spaces, leading up to the spectral theory of unbounded self-adjoined operators; - the application to linear Hamiltonian systems, giving the details of the spectral resolution; - further applications such as to orthogonal polynomials and Sobolev differential operators. Written in textbook style this up-to-date volume is geared towards graduate and postgraduate students and researchers interested in boundary value problems of linear differential equations or in orthogonal polynomials.Krall, Allan M. is the author of 'Hilbert Space, Boundary Value Problems and Orthogonal Polynomials' with ISBN 9783764367015 and ISBN 3764367016.
