摘　　要：In this article, we investigate the existence of periodic solutions for a class of nonautonomous second-order differential systems with p(t)-Laplacian. Some multiplicity results are obtained by using critical point theory, which extend some known results.In this article, we investigate the existence of periodic solutions for a class of nonautonomous second-order differential systems with p（t）-Laplacian.
