Title: Prufer transformation for the p-Laplacian Authors: Jiri Benedikt (Univ. of West Bohemia, Czech Republic) Petr Girg (Univ. of West Bohemia, Czech Republic) Abstract: Prufer transformation is a useful tool for study of second-order ordinary differential equations. There are many possible extensions of the original Prufer transformation. We focus on a transformation suitable for study of boundary value problems for the p-Laplacian in the resonant case. The purpose of this paper is to establish its basic properties in deep detail. Published July 10, 2010. Math Subject Classifications: 34A12, 34A34, 34B15. Key Words: Prufer transformation; p-Laplacian; jumping nonlinearity.
