Title: On a problem of lower limit in the study of nonresonance with Leray-Lions operator Authors: Aomar Anane (Univ. Mohammed 1er, Oujda, Maroc) Omar Chakrone (Univ. Mohammed 1er, Oujda, Maroc) Mohammed Chehabi (Univ. Mohammed 1er, Oujda, Maroc) Abstract: We prove the solvability of the Dirichlet problem $$\displaylines{ Au = f(u)+h \quad\text{in } \Omega , \cr u = 0 \quad\text{on }\partial \Omega }$$ for a given $h$, under a condition involving only the asymptotic behaviour of the potential $F$ of $f$, where $A$ is a Leray-Lions operator.
