Abstract. In this paper we have present new oscillation and non-oscillation criteria for nonlinear differential equations of second order with damping term
Also by using the generalized Riccati technique and positive function of Phillo we get a new oscillation and non-oscillation criteria for (1). The result is different from most known ones and improve some previous oscillation criteria and cover the cases which are not covered by known results.
