Electronic Journal of Differential Equations, Conference 08 (2002), pp. 35-46 Title: Some Liouville theorems for the $p$-Laplacian Authors: Isabeau Birindelli (Univ. de Cergy Pontoise, France) Francoise Demengel (Univ. de Cergy Pontoise, France) Abstract: In this paper we propose a new proof for non-linear Liouville type results concerning the $p$-Laplacian. Our method differs from the one used by Mitidieri and Pohozaev because it uses a comparison principle that can be applied to nondivergence form operators Published October 21, 2002.
