| 摘 要： | Recently there has been a considerable amount of work on the existence of Tperiodic solutions for Hamiltonian systems with singular potentials, (see 1]—7],10], 11], 13], 14]). In this paper we will study the existence of T-periodic solutions for nonconservative second-order dynamical systems |
