Abstract
In this paper, we are interested on the study of the nonexistence of nontrivial solutions for the p(x)-Laplacian equations, in unbounded domains of ℝ n . This leads us to extend these results to m-equations systems. The method used is based on pohozaev type identities.

Summary
Several works have been reported by many authors, comprise results of nonexistence of nontrivial solutions of the semilinear elliptic equations and systems, under various situations, see [1,2,3,4,5,6,7,8]. In this work we are interested in the study of the nonexistence of nontrivial solutions for the p(x)-laplacian problem. Ω is bounded or unbounded domains of Rn, f is a locally lipshitzian function, H and p are given continuous real functions of C( ̄ ) verifying t. (., .) is the inner product in Rn We extend this technique to the system of m-equations. Where {fk} are locally lipshitzian functions verify fk(s1, ..., sk−1, 0, uk+1, ..., sm) = 0, (0 ≤ k ≤ m),. H is previously defined and pk functions of C1( ) class, verify pk(x) > 1, (x, ∇pk(x)) ≥ 0, ∀x ∈ ̄
