Le but de cette Note est de donner des conditions suffisantes, dites λ-bonnes généralisées, pour la comparaison de deux fonctions mesurables dans les espaces de Lorentz pondérés. De plus, nous présentons des applications de ces résultats aux estimations de gradient des solutions aux problèmes elliptiques quasi linéaires dans les espaces de Lorentz pondérés.

The aim of this paper is to give some sufficient conditions, called generalized good-λ conditions, to obtain the weighted Lorentz comparisons between two measurable functions. Moreover, we also present several applications of these results for the gradient estimates of solutions to quasilinear elliptic problems in weighted Lorentz spaces.
