摘要
本文利用重合度拓展定理,研究了一类p-Laplacian中立型泛函数微分方程(φp((x(t)-c(t)x(t-r))′))′=g(x(t-r(t)))+e(t)。在C(t)变号的情况下,得到了方程周期解存在性的一个新结果。
In this paper,we study the existence of periodic solutions to a p-Laplacian neutral functional differential equation as follows(φp ((x(t) -c(t)x(t-r))'))' =g(x(t-r(t))) +e(t). It is meaningful that c(t) is not a constant function and can change sign, which is different from the corresponding ones of known literature.
