We present new oscillation criteria for the second order nonlinear damped delay dynamic equation (r(t)(x(t))) + p(t)(x(t)) + q(t)f (x(τ(t))) = 0. Our results generalize and improve some known results for oscillation of second order nonlinear delay dynamic equation. Our results are illustrated with examples.

By means of Riccati transformation technique, we establish some new oscillation criteria for the second-order nonlinear delay dynamic equations r t xΔ t γ Δ p t f x τ t 0 on a time scale T; here γ > 0 is a quotient of odd positive integers with r and p real-valued positive rdcontinuous functions defined on T. Our results not only extend some results established by Hassan in 2008 but also unify ...
