Abstract

In this paper, we study the oscillations of a kind of second-order nonlinear delay differential equations with variable sign oscillation factors. Three sufficient conditions about the equation are obtained, which generalize the present oscillation results of second-order nonlinear differential equations and delay differential equations with invariable sign coefficients.
