Periodic solutions for a kind of Liénard equation
The authors reconsider periodic solutions of a Liénard equations with delay. The main purpose of this paper is to establish a new sufficient condition for the existence and uniqueness of \(T\)-periodic solutions of the equation. Using inequality techniques and coincidence degree theory, new results are provided concerning the existence and uniqueness of \(T\)-periodic solutions for a Liénard equations with delay. An illustrative example is provided.
