摘要
In this paper, we are concerned with the existence of periodic solutions for second order non-autonomous Hamiltonian systems under a new subquadratic growth condition. By using the minimax methods in critical point theory, an existence theorem is obtained, which extends and improves some known results in the literature. (C) 2014 Elsevier Ltd. All rights reserved.
