Existence of solutions to superlinear p-Laplace equations without Ambrosetti-Rabinowizt condition

Duong Minh Duc

Abstract:
We study the existence of non-trivial weak solutions in $W^{1,p}_{0}(\Omega)$ of the super-linear Dirichlet problem
$$\displaylines{
 - \hbox{div}(|\nabla u|^{p-2}\nabla u)=f(x,u) \quad \text{in }\Omega,\cr
 u=0 \quad \text{on }\partial\Omega,
 }$$
where f satisfies the condition
$$
 |f(x,t)|\leq |\omega(x)t|^{r-1} + b(x)\quad \forall (x,t) \in
 \Omega\times \mathbb{R},
 $$
where $r\in (p,\frac{Np}{N-p})$, $b\in L^{\frac{r}{r-1}}(\Omega)$ and $|\omega|^{r-1}$ may be non-integrable on $\Omega$.
