Abstract
In this paper, we give a new sufficient condition for oscillation of first-order delay dynamic equations on time scales, which generalize the main results of the papers [Proc. Amer. Math. Soc. 124 (1996), no. 12, 37293737] by Li and [Comput. Math. Appl. 37 (1999), no. 7, 1120] by Tang and Yu. To emphasize the significance of the new result, an example for which all the results fail is also given on a nonstandard time scale. Copyright (c) 2013 John Wiley & Sons, Ltd.
