Existence of Homoclinic Orbits for Hamiltonian Systems with Superquadratic Potentials
Keyword(s):
This paper concerns solutions for the Hamiltonian system:z˙=𝒥Hz(t,z). HereH(t,z)=(1/2)z⋅Lz+W(t,z),Lis a2N×2Nsymmetric matrix, andW∈C1(ℝ×ℝ2N,ℝ). We consider the case that0∈σc(−(𝒥(d/dt)+L))andWsatisfies some superquadratic condition different from the type of Ambrosetti-Rabinowitz. We study this problem by virtue of some weak linking theorem recently developed and prove the existence of homoclinic orbits.
