Abstract: This paper  investigates the existence of solutions for periodic boundary value of discrete p(k)-Laplacian systems.Under the generalized subquadratic conditions,some results for the existence of periodic solutions are obtained by using the saddle point theorem,and the validity of the solvability conditions is proved.

Key words: difference systems, variable exponent, critical point, periodic solution
