“…We refer to the books [4,5,6] for the introduction of the theory of impulsive differential equations. The study of impulsive dynamic equations on time scales has also attracted much attention because it provides an unifying structure for differential equations in the continuous cases and finite difference equations in the discrete cases; see, [7,8,9,10,11,12,13,14,15,16,17,18] and references therein.…”
