By using a Picone type formula in comparison with oscillatory unforced half-linear equations, we derive new oscillation criteria for second order forced super-half-linear impulsive differential equations having fixed moments of impulse actions. In the superlinear case, the effect of a damping term is also considered.
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(More)
