Abstract

In this paper, we investigate the following nonlinear and non-homogeneous elliptic system \[ \begin{cases} -div(\phi_1(|\nabla u|)\nabla u)= F_u(x,u,v),\,\,\,\,\, \texttt{in} \Omega,\\ -div(\phi_2(|\nabla v|)\nabla v)= F_v(x,u,v),\,\,\,\,\, \texttt{in} \Omega,\\ u=v=0,\,\,\,\,\, \texttt{on} \partial \Omega. \end{cases} \] where \(\Omega\) is a bounded domain in \(R^N(N \geq 2)\) with smooth boundary \(\partial\Omega\) , functions \(\phi_i(t)t (i = 1, 2)\) are increasing homeomorphisms from \(R^+\) onto \(R^+\). When \(F\) satisfies some \((\phi_1,\phi_2)\)-superlinear and subcritical growth conditions at infinity, by using the mountain pass theorem we obtain that system has a nontrivial solution, and when \(F\) satisfies an additional symmetric condition, by using the symmetric mountain pass theorem, we obtain that system has infinitely many solutions. Some of our results extend and improve those corresponding results in Carvalho et al. [M. L. M. Carvalho, J. V. A. Goncalves, E. D. da Silva, J. Math. Anal. Appl., 426 (2015), 466–483].
