“…Such phenomena are often modeled by impulsive differential equations and inclusions. Some good discussions and results on impulsive equations can be found in the monographs by Bainov, Lakshmikantham, and Simeonov [3], Djebali, Gorniewicz, and Ouahab [6], Graef, Henderson, and Ouahab [7], and Perestyuk, Plotnikov, Samoilenko, and Skripnik [13] and the references therein. Using fixed point arguments, existence as well as uniqueness results for some classes of impulsive boundary differential equations and dynamic equations were given by Benchohra and Eloe [4], Graef and Ouahab [9], and Nieto [12], among others.…”
