摘要 利用Banach压缩映象原理,研究下列n阶中立型时滞微分方程dn/dtn[x(t)+cx(t-T1)+dx(t-T2)]+(-1)(n+1)f(t,x(t-σ1),x(t-σ2),···,x(t-σk))=g(t)的非振动解的存在性,并获得了相应非振动解的迭代逼近序列以及误差估计. Using the Banach contraction mapping theorem,sufficient conditions for the existence of nonoscillatory solutions for a class of nth-order neutral delay differential equation are obtained.In addition,iterative approximation sequences of corresponding nonoscillatory solutions and the error estimate are obtained.
