摘要
本文讨论一阶非线性中立型方程组[yi(t)-∑Cij(t,yj(t-σij(t)))'+fi(t,y1(t),…,yn(gin(t))=0,i=1,2,…n的非振动解的存在性,得到了一些新的结果。
We obtain some sufficient conditions by means of discussing the existence for nonoscillatory solution of first order nonlinear neutral functional differential equations. [yi(t)-∑Cij(t,yj(t-σij(t)))'+fi(t,y1(t),…,yn(gin(t))=0,i=1,2,…n
