Abstract
Thanks to a change of unknown we compare two elliptic quasilinear problems with Dirichlet data in a bounded domain of R-N. The first one, of the form -Delta(p)u = beta(u)|del u|(p) + lambda f(x), where beta is nonnegative, involves a gradient term with natural growth. The second one of the form -Delta(p)u = lambda f(x)(1 + g(v))(p-1) where g is nondecreasing, presents it source term of order 0. The correlation gives new results of existence, nonexistence and Multiplicity for the two problems. To cite this article: H.A. Hamid, M.E Bidaut-Veron, C R. Acad. Sci. Paris, Ser. I 346 (2008).
