This paper deals with existence and exponential decay of homoclinic orbits in the first-order Hamiltonian systemover(z, ̇) = J Hz (t, z) where the Hamiltonian function H (t, z) is nonperiodic in t ∈ R and superquadratic in z ∈ R2 N. With certain mild conditions we obtain the solutions via variational methods for strongly indefinite problems.
