Oscillation for second order nonlinear differential equations with a sub-linear neutral term

Yingzhu Wu, Yuanhong Yu, Jinsen Xiao

Abstract:
We study the oscillatory behavior of solution to the second order nonlinear differential equations with a sub-linear neutral term

A new criterion is established that improves related results reported in the literature. Moreover, some examples are provided to illustrate the main results.
