摘要
We are interested in the asymptotic behavior of solutions of a Schrodinger-type equation with oscillating potential which was studied by A. Its. Here we use a different technique, based on Levinson's Fundamental Lemma, to analyze the asymptotic behavior, and our approach leads to a complete asymptotic representation of the solutions. We also discuss formal simplifications for differential equations with what might be called "regular/irregular singular points with periodic coefficients". (c) 2006 WILEY-VCH Verlag GmbH & Co.
