We investigate solutions for nonlinear operator equations and obtain some abstract existence results by linking methods. Some well-known theorems about periodic solutions for second-order Hamiltonian systems by M. Schechter are special cases of these results.

Keywords: Operator equations, critical points, linking, existence of solution, second-order Hamiltonian systems.
