Correlation between two quasilinear elliptic problems with a source term involving the function or its gradient
Comptes Rendus de l Académie des Sciences - Series I - Mathematics 346 (2008) 1251-1256
Abstract: Thanks to a change of unknown we compare two elliptic quasilinear problems with Dirichlet data in a bounded domain of $\mathbb{R}^{N}.$ The first one, of the form $-\Delta_{p}u=\beta(u)\left\vert \nabla u\right\vert ^{p}+\lambda f(x),$ where $\beta$ is nonnegative, involves a gradient term with natural growth. The second one, of the form $-\Delta_{p}v=\lambda f(x)(1+g(v))^{p-1}$ where $g$ is nondecreasing, presents a source term of order $0$. The correlation gives new results of existence, nonexistence and multiplicity for the two problems.
