Abstract

A class of third order differential equations with several sublinear neutral terms of the type

(a(t)(b(t)(x(t)+j=1npj(t)xαj(τj(t)))))+i=1mfi(t,x(σi(t)))=0,tt0>0

is considered. Some oscillation criteria are presented to improve and complement those in the literature. Two examples are established to illustrate the main results.
