【Abstract】 We discuss oscillation criteria for second-order half-linear delay dynamic equations with damping on a time scale, by using the generalized Riccati transformation and the inequality technique. Under certain conditions, we establish four new oscillation criteria. Our results improve and extend some known results.更多还原
