摘要
In this paper we are concerned with the existence of nontrivial periodic solutions of an asymptotically linear Hamiltonian systems when a kind of resonance condition is satisfied. We prove several new existence results via the Morse theory, the Garlerkin methods, and the Moslov index theory. (C) 1998 Academic Press.
