Abstract
In this paper, we investigate the existence of periodic solutions for the nonlinear discrete system with classical or bounded
(\(\phi_1,\phi_2\))-Laplacian: \[
\begin{cases}
\Delta\phi_1(\Delta u_1(t-1))+\nabla_{u_1}F(t,u_1(t),u_2(t))=0,\\
\Delta\phi_2(\Delta u_2(t-1))+\nabla_{u_2}F(t,u_1(t),u_2(t))=0.
\end{cases}
\]
By using the saddle point theorem, we obtain that system with classical (\(\phi_1,\phi_2\))-Laplacian has at least one periodic solution
when F has (p, q)-sublinear growth, and system with bounded (\(\phi_1,\phi_2\))-Laplacian has at least one periodic solution when \(F\) has
(\(p,q\))-sublinear growth. By using the least action principle, we obtain that system with classical or bounded (\(\phi_1,\phi_2\))-Laplacian has at
least one periodic solution when \(F\) has a growth like Lipschitz condition.
