摘要
考虑时标上具有正负系数的二阶非线性中立型动力方程正解的存在性,首先构造适当的时标上的连续算子,再利用Banach压缩映射原理,最后得出其正解存在的充分条件。
This paper studied the existence of non-oscillatory solutions for the second-order nonlinear dynamic equations with the positive and negative coefficients. By defining continuous operators and using Banach fixed theorem on the time scales, the sufficient condition of the existence of positive oscillatory solutions for the a- bove equations is obtained.
