Twin periodic solutions of predator-prey dynamic system on time scales

Abstract

In this article, we consider a delayed predator-prey dynamic system with type IV functional responses on time scales. Sufficient criteria for the existence of at least two periodic solutions are established by using the well-known continuation theorem due to Mawhin. An example is given to illustrate the main result.
