| Abstract: | By using the theory of Fourier series, Bernoulli number theory and continuation theory of coincidence degree theorem, we study a kind of high-order functional di erential equation with distributed delay as follows:x(m)(t)+f(x(m-1)(t))+g(∫o-rx(t + s)dα(s)) = p(t).Some new results on the existence of periodic solutions are obtained. |
