2006, Mathematical and Computer ModellingCitation Excerpt :In this paper, our purpose is to derive a set of easily verifiable sufficient conditions for the existence and attractivity of positive periodic solutions for system (1.1). Existing results on the existence and attractivity of positive periodic solutions in periodic population models often fall into one of the following two categories: (1) the results of the application of the contraction principle or fluctuation principle, which establish both the existence and attractivity of the periodic solutions in periodic population models with time delay (Kuang [14, p. 181]); (2) the results of application of coming Brower fixed point theorem and Lyapunov functional with the results of persistence of positive solutions, which first establish the existence of positive periodic solutions in periodic population models with time delays by using the Brower fixed point theorem and the results of persistence of positive solutions, then establish the attractivity of positive periodic solutions in periodic population models by using a Lyapunov functional [15–17]. Though these methods often allow the investigator to address the stability issues of the positive periodic solution of population models, the conditions for the existence part are often unnecessarily numerous, tedious, stringent, and difficult to satisfy.
