Title: Periodic solutions for a food chain system with Monod-Haldane functional response on time scales Author: Kejun Zhuang (Anhui Univ. of Finance and Economics, Bengbu, China) Abstract: In this article, we study a three species food chain model on time scales, with Monod-Haldane functional response and time delay. With the help of coincidence degree theory, we establish the existence of periodic solutions. Submitted July 7, 2012. Published February 21, 2014. Math Subject Classifications: 92D25, 34C25.
