摘要
应用Banach压缩不动点原理研究了一类高阶非线性变系数中立型微分方程非振动解的存在性,改进了相关文献的结果.
It studies the existence of nonoscillatory solutions of variable coefficient higher order nonlinear neutral differential equations by the Banach contraction principle. Some new sufficient conditions have been obtained, which improves the results in the literature.
