摘要:In this talk, we first discuss the existence of homoclinic orbits for a class of asymptotically quadratic second order Hamiltonian systems. Via the variational method, two new theorems are proved. Then we discuss a class of second-order asymptotically periodic Hamiltonian systems. Under reformative conditions and a weaker superquadratic condition on the nonlinearity, the existence of ground state homoclinic orbits is obtained. The main tools employed are the Local Mountain Pass Theorem and the Concentration-Compactness Principle.
