### On a generalization of Lazer-Leach conditions for a system of second order ODE's

#### Abstract

We study the existence of periodic solutions for a nonlinear second order system of ordinary differential equations. Assuming suitable Lazer-Leach type conditions, we prove the existence of at least one solution applying topological degree methods.
