Periodic Solution For Predator-Prey Dynamic System On Time Scales With Holling-Typeâ…¡ Functional Response

In this paper, we explore the existence of a periodic solution for density-dependent predator-prey system with Holling-tpyell functional response on time scales . By using the method of coincidence degree, a set of easily verifiable sufficient conditions are established for the existence of positive periodic solution of this system.
