WKB and Turning Point Theory for Second-order Difference Equations,A turning point method for difference equations is developed. This method is coupled with the LG-WKB method via matching to provide approximate solutions to the initial value problem. The techniques developed are used to provide strong asymptotics for Hermite polynomials.

Free Functional Model Related to Simply-connected Domains,The aim of this paper is to extend the S.-Nagy-Foias functional model to the case of functions for contractive operators. This model meets general requirements and can be used for studying trace class perturbations of normal operators with spectrum on a curve.
