Abstract

Abstract

In this paper,by using of the theory of coincidence degree,we obtain the new conditions which guarantee the existence of harmonic solutions for Liénard Systems Our resuls do not require that the damping must be positive.
- Liénard systems,
- harmonic solutions,
- coincidence degree
