Abstract

In this work, we consider an elliptic system
\begin{eqnarray}
\left\{ \begin{array}{cc}
-\triangle u = au + bv + \delta_1 u^+ -\delta_2 u^- +f_1 (x,u,v) \qquad \text{ in } \Omega, \\
-\triangle v = bu + cv + \eta_1 v^+ -\eta_2 v^- +f_2 (x,u,v) \qquad \text{ in } \Omega, \\
u=v=0 \qquad \qquad \qquad \text{ on } \partial \Omega,
\end{array}
\right. \nonumber
\end{eqnarray}
where $\Omega \subset R^{N}$ be a bounded domain with smooth
boundary. We prove that the system has at least
two nontrivial solutions by applying linking theorem.
