Title: Picone's identity for the p-biharmonic operator with applications

Author: Jaroslav Jaros (Comenius Univ., Bratislava, Slovakia)

Abstract:
 In this article, a Picone-type identity for the weighted
 p-biharmonic  operator is established and comparison results
 for a class of half-linear partial differential equations of
 fourth order based on this  identity are derived.
