Spectra of Differential Operators

Horst Behnke, Universität Osnabrück


The spectra of differential operators of the form

$\displaystyle Ly=w^{-1} \sum ^n _{K=0} (-1)^K (p_K y ^{(K)}) ^{(K)}$

on $ [0, \infty)$ are investigated. The coefficients are assumed to be real valued and locally integrable, $ p_n (x), w(x)> 0$, and satisfy conditions which combine decay at infinity and smoothness. In this case the selfadjoint extensions of the corresponding minimal operator have no singular continuous spectrum and the absolutely continuous spectrum can be characterized completely.
