| Abstract: |
| Using the Mawhin continuation theorem, this paper studies a class of periodic solutions of the second order differential equation with deviating arguments x″(t)+ f(t,x(t),x(t－τ0(t)),x′(t))+β(t)g(x(t－τ1(t)))=p(t), and two sufficient conditions of the periodic solutions are obtained. |
| Key words: the Mawhin continuation theorem deviating arguments periodic solutions |
