摘要
In this paper, we study the existence of periodic solutions for a p-Laplacian neutral functional differential equation, as follows (phi(p)(x'(t) - c(t)x'(t - r)))' = f(x(t))x'(t) + beta(t)g(x(t - tau(t))) + e(t). It is meaningful that c(t) is not a constant function, and that the functions c(t) and beta(t) are allowed to change signs, which are different from the corresponding ones of known literature.
