Faycal Bouchelaghem, Abdelouaheb Ardjouni, Ahcene Djoudi

• In this article we study the existence of positive periodic solutions for a dynamic equations on time scales. The main tool employed here is the Schauder’s fixed point theorem. The results obtained here extend the work of Olach [12]. Two examples are also given to illustrate this work.
