We investigate the existence of infinitely many periodic solutions for the p(t)-Laplacian Hamiltonian systems. By virtue of several auxiliary functions, we obtain a series of new super -p(+) growth and asymptotic -p+ growth conditions. Using the minimax methods in critical point theory, some multiplicity theorems are established, which unify and generalize some known results in the literature. Meanwhile, we also present an example to illustrate our main results are new even in the case p(t) = p = 2.
