| Abstract: | The oscillation of neutral functional differential equations has important implications in both theory and application.We study the oscillation of a class of second order nonlinear neutral delay functional differential equations with positive and negative coefficients.Using the Banach contraction mapping principle and some analytic techniques,some new nonoscillation criteria for the equation are established,and illustrative examples are given.Existing results in the literature are improved and extended. |
| Keywords: | positive and negative coefficient neutral functional differential equation nonlinear oscil- lation nonoscillation |
