An Application of Value Distribution Theory to Schroedinger Operators   with Absolutely Continuous Spectrum
  We use the "Value Distribution" theory developed by Pearson and Breimesser to obtain a sequence of functions in the eigenvalue parameter for some Sturm-Liouville problems which have the property of being "uniformly asymptotically distributed".
