[Sur un principe de comparaison de type Liouville pour des solutions d'inégalités elliptiques quasi-linéaires]
On caractérise en terme de monotonie, des propriétés fondamentales d'opérateurs aux dérivées partielles, elliptiques, quasi-linéaires permettant d'établir un principe de comparaison de type Liouville, des solutions faibles d'inégalités aux dérivée partielles, elliptiques, quasi-linéaires de la forme A(u)+|u|q−1u⩽A(v)+|v|q−1v. Ces solutions appartiennent seulement localement aux espaces de Sobolev correspondant dans . On montre que ces propriétés sont valables pour une large classe d'opérateurs aux dérivées partielles elliptiques, quasi-linéaires. Des exemples typiques de tels opérateurs sont le p-laplacien et ses modifications bien connues pour 1<p⩽2.
We characterize in terms of monotonicity basic properties of quasilinear elliptic partial differential operators which make it possible to obtain a Liouville-type comparison principle for entire solutions of quasilinear elliptic partial differential inequalities of the form A(u)+|u|q−1u⩽A(v)+|v|q−1v, which belong only locally to the corresponding Sobolev spaces on . We establish that such properties are inherent for a wide class of quasilinear elliptic partial differential operators. Typical examples of such operators are the p-Laplacian and its well-known modifications for 1<p⩽2.
