| Abstract: |
| In this paper,we investigate a class of non-autonomous p(t-Laplacian system.By using saddle point theorem and the least action principle,some sufficient conditions for the existence of periodic solutions are obtained,which generalize and improve the resuls in[8]. |
| Key words: periodic solutions p(t)-Laplacian systems critical point |
