Examples of Sobolev Differential OperatorsFrom each section of the previous chapter we list at least one example. For the singular problems there are several.

Regular Linear Hamiltonian Systems L. Wilder and L. Schlesinger. G. A. Bliss in 1926 seems to have been the first to discuss regular, self-adjoint differential systems. Additional references to their works may be found in the papers of Birkhoff and Langer , and in the book by Coddington and Levinson.

The Spectral Resolution for Linear Hamiltonian Systems with One Singular Pointperators in a Hilbert space, looks like when applied to the self-adjoint linear Hamiltonian systems of Hinton and Shaw. Remarkably we can find detailed formulas for the spectral measure and the Hilbert space it generates, far more than is possible for the setting employed by Niessen.

0255-0156systemsand their scalar counterparts and their application to orthogonal polynomials. In a sense, this is an updating of E. C. Titchmarsh‘s classic Eigenfunction Expansions. My interest in these areas began in 1960-61, when, as a graduate student, I was introduced by my advisors E. J. McShane and M
