摘要
我们利用Mawhin重合度拓展定理,研究了一类二阶时滞泛函微分方程x″(t)+f(t,x(t),x(t-τ))=p(t)周期解的存在唯一性问题,得到了其周期解存在唯一的新的结果.
In this paper, the authors employ the theory of Mawhin' s continuation theorem to study the existence and uniqueness of periodic solutions for a kind of second order functional differential equations with a deviating argument: x″(t)+f(t,x(t),x(t-τ))=p(t) Some new results on the existence and uniqueness of periodic solutions are obtained.
