Abstract :
TIn this paper, the existence of periodic solutions of a predator-prey model with Beddington-DeAngelis type functional response is investigated by using the Gaines and Mawhin;s continuation theorem of coincidence degree theory on time scales. Some conditions are obtained for the existence of periodic so- lutions. The approach is uni ed to provide the existence of the desired solutions for the continuous di erential equations and discrete di erence equations.
