Finiteness of the Spectrum of Boundary Value Problems

Short Communications


We consider boundary value problems with spectral parameter polynomially occurring in the differential equation or the boundary conditions. It is shown that some of these problems have a prescribed finite spectrum. A wide class of boundary value problems which do not have finite spectrum exist is found.
