Oscillation for a Class of Second-Order Emden-Fowler Delay Dynamic Equations on Time Scales

摘要

By means of Riccati transformation technique, we establish some new oscillation criteria for the second-order Emden-Fowler delay dynamic equations on a time scale ; here is a quotient of odd positive integers with and as real-valued positive rd-continuous functions defined on . Our results in this paper not only extend the results given in Agarwal et al. (2005), Akin-Bohner et al. (2007) and Han et al. (2007) but also unify the results about oscillation of the second-order Emden-Fowler delay differential equation and the second-order Emden-Fowler delay difference equation.
