Abstract:
In this work, we prove the existence and uniqueness of periodic
solutions for a Lienard equation with two deviating arguments.
Our main tools are the Mawhin's continuation theorem and
the Schwarz inequality. We obtain our results under weaker
conditions than those in [14], as shown by an example in
the last section of this artticle.
