摘要
We study the existence of 2 pi-periodic solutions of the second order Hamiltonian systems -sic- A(t)sic = lambda x + nu'sic(t, sic) with superlinear terms and with saddle structure near the origin. Some multiplicity results are obtained by using bifurcation method, homological linking and Morse theory. (c) 2011 Elsevier Inc. All rights reserved.
