Oscillation theory for canonical systems, applications, and a couple of other things
Abstract
Oscillation theory for canonical systems is developed. This is then applied to various topics related to semibounded systems and the essential spectrum. The correspondence between self-adjoint relations and self-adjoint operators coming from canonical systems is investigated. An upper bound on the number of solutions of a one-channel difference equation is obtained.
