摘要:The purpose of this article is to give oscillation criteria for the third-order neutral dynamic equation ( r 2 ( t ) [ ( r 1 ( t ) [ y ( t ) + p ( t ) y ( τ ( t ) ) ] △ ) △ ] γ ) △ + f ( t , y ( δ ( t ) ) ) = 0 , where γ ⩾ 1 is a ratio of odd positive integers with r 1 ( t ) , r 2 ( t ) , and p ( t ) are positive real-valued rd-continuous functions defined on T . We give new results for the third-order neutral dynamic equations and an example to illustrate the importance of our results.
