Abstract: By means of better prior estimate and the topologial degree, the existence of periodic solutions to a class of the second order functional differentialiterative equations x¨(t)+g(x(x(t)))=f(t,x(t),x·(t)) was studied, and sufficient conditions of the equation with periodic solutions were obtained.

Key words: functional differentialiterative equation, periodic solution, topologial degree
