摘要：
By means of variational structure and critical point theory, we study the existence of periodic solutions for a second-order neutral differential equation (p(t)x'(t - T))' + f(t, x(t),x(t - T),x(t - 2T)) = g(t), x(0) = x(2kt),x'(0) = x'(2kT). where k is a given postitive integer and T is a positive number.
