On the oscillation of third order neutral delay dynamic equations on time scales

Han et al. [Z. Han, T. Li, S. Sun, C. Zhang, Oscillation behavior of third order neutral Emden-Fowler delay dynamic equations on time-scales, Adv. Differential Equations 2010 (2010). Article ID 586312, 23 pages] gave some criteria for the oscillation and asymptotic behavior of solutions of the third order neutral delay dynamic equation (r(t) (x(t) - a(t)x (tau (t)))(Delta Delta))(Delta) + p(t)x(gamma) (delta(t)) = 0 on a time scale T, where gamma > 0 is the quotient of odd positive integers. In this paper, the authors establish some new criteria for the oscillation of this equation that improve and unify those of Han et al. (c) 2011 Elsevier Ltd. All rights reserved.
