Abstract:

In this paper, by using the abstract continuation theorem of k-set contractive operator and some analysis
techniques, the authors study the existence of periodic solutions for a kind of second order functional differential equations with deviating arguments. The results improve and extend the main results of the papers [1-2].

Key words: Periodic solution, Deviating argument, Functional differential equation, k-set contractive operator
