It is the aim to confront recent considerations of A. M. KRALL on the left-definite spectral theory of regular Hamiltonian systems with the results of former research in this field. A short survey of the main sources starting with the work of E . HOLDER in 1935 is given. After that the essential fea

Abstract
Linear Hamiltonian systems allow us to generalize, as well as consider, self‐adjoint problems of any even order. Such left‐definite problems are interesting, not only because of the generalization, but also because of the new intricacies they expose, some of which have made it possible to go beyond fourth order scale problems.
We explore the left definite Sobolev settings for such problems, which are in general subspaces determined by boundary conditions. We show that the Hamiltonian operator remains self‐adjoint, and inherits the same resolvent and spectral resolution from its original L^2^ space when set in the left‐definite Sobolev space.

## Abstract The left‐definite boundary conditions of the problem consisting of a regular formally self‐adjoint differential equation of even order and a self‐adjoint boundary condition are characterized in terms of a certain fundamental set of solutions of the equation. Based on the left‐definite b
An alternative approach to secular problems for Hamiltonian matrices H of regular quasi-one-dimensional systems is suggested. The essence of this approach consists of the inverted order of operations against that of the traditional solid-state theory, viz., taking into account the local structure of
