We deal with the existence of constant sign solutions for the following variable exponent system Neumann boundary value problem: in in on . We give several sufficient conditions for the existence of the constant sign solutions, when satisfies neither sub-() growth condition, nor Ambrosetti-Rabinowitz condition (subcritical). In particular, we obtain the existence of eight constant sign solutions.
