Abstract

We use classical Leray-Schauder techniques and the coincidence degree in order to obtain the existence or periodic solutions of forced Liénard systems with distinct delays, under nonuniform conditions. The resonance and nonresonance case with respect to the eigenvalue zero are considered.
