摘要:By means of Riccati transformation technique, we establish some new oscillation criteria for the third-order nonlinear delay dynamic equations x ∆ 3 (t) + p(t)x γ (τ(t)) = 0 on a time scale T unbounded above, here γ > 0 is a quotient of odd positive integers with p real-valued positive rd-continuous function defined on T. Three examples are given to illustrate the main results.
