摘要
研究一类带时滞的二阶微分方程解的存在性与唯一性问题,利用重合度方法与Wrintinger不等式,得出若干新的结果。
In this paper,we analyse the problem on the existence and uniqueness of periodic solutions for a kind of second order differential equations with a deviating argument of the form.By means of the coincidence degree theory and Writinger inequalities,a new result is obtained under some conditions.
