Abstract

Some news sufficient conditions for oscillation of all solutions of a class of second order differential equations with several sub-linear neutral terms are given. Our results not only extend several classical oscillation theorems but also improve and generalize those reported in the literature, recently. Examples are included to illustrate the importance of the results obtained.

Key words

neutral differential equation / sub-linear neutral term / oscillation criterion
