摘要
本文研究两类高阶偏泛函微分方程系统的强迫振动性,利用微分不等式和积分技巧,获得了这两类系统解的强迫振动的若干充分判据,所得结果推广和包含了文[1]的相应结果.
In this paper,we investigate the forced oscillation of solutions for two kinds of systems of higher order partial functional differential equations. Some sufficient criteria are obtained by using differential inequality and integral technique. These results generalize the corresponding results of paper.
