Abstract: 
 In this paper the authors study the existence of local weak
 solutions of the strongly nonlinear system
 $$\displaylines{
 u''+\mathcal{A}u +f(u,v)u = h_1 \cr
 v''+\mathcal{A}v +g(u,v)v = h_2
 }$$
 where $\mathcal{A}$ is the pseudo-Laplacian operator and $f$,
 $g$, $h_1 $ and $h_2 $ are given functions.
