On Homoclinic Solutions for First-Order Superquadratic Hamiltonian Systems with Spectrum Point Zero

[摘要] The existence and multiplicity of homoclinic solutions for a class of first-order periodic Hamiltonian systems with spectrum point zero are obtained. The proof is based on two critical point theorems for strongly indefinite functionals. Some recent results are improved and extended.
