Algorithms for estimating spectral density functions for periodic potentials on the half line
Charles Fulton, David Pearson, Steven Pruess
For Hill's equation on [0,infinity) we prove new characterizations of the spectral function rho(lambda) and the spectral density function f(lambda) based on analysis involving a co…

Estimating Spectral Density Functions for Sturm-Liouville problems with two singular endpoints
Charles Fulton, David Pearson, Steven Pruess
In this paper we consider the Sturm-Liouville equation -y"+qy = lambda*y on the half line (0,infinity) under the assumptions that x=0 is a regular singular point and nonoscillatory…
