In this paper we study the existence of nontrivial solutions for the following system of two coupled semilinear Poisson equations: - Deltau = g(u), v > in Omega, (S) -Deltau = f (u), u > in Omega, u = 0, v = 0, on partial derivativeOmega, where Omega is a bounded domain in R-2 with smooth boundary partial derivativeOmega, and the functions f and g have the maximal growth which allow us to treat problem (S) variationally in the Sobolev space H-0(1) (Omega). We consider the case with nonlinearities in the critical growth range Suggested by the so-called Trudinger-Moser inequality
