A multi-interval quasi-differential system $/{I_{r}, M_{r}, w_{r}:r/in/Omega/}$ consists of a collection of real intervals, $/{I_{r}/}$, as indexed by a finite, or possibly infinite index set $/Omega …

This investigation introduces a new description and classification for the set of all self-adjoint operators (not just those defined by differential boundary conditions) which are generated by a line …

Complex symplectic spaces, defined earlier by the authors in their AMS Monograph, are non-trivial generalizations of the real symplectic spaces of classical analytical dynamics. These spaces can also …
