Abstract

This paper investigates the distribution of zeros of oscillatory solutions for a certain class of second order nonlinear neutral differential equations. By constructing some new function sequences and the properties of solutions for the corresponding first order differential inequality, several further results for the distance between adjacent zeros and sufficient conditions for oscillation are given, which generalize and extend some known results.
