Multiple Periodic Solutions for a General Class of Delayed Cooperative Systems on Time Scales
Authors: ,
Abstract: In this paper, we consider a general class of delayed nonautonomous logistic Lotka-Volterra type multi- species cooperative system with harvesting terms on time scales. The model invovles the intraspecific cooperative terms defined by functions which depend on population densities. An existence theorem of at least 2n periodic solutions is established by using the coincidence degree theory. An example is given to illustrate the effectiveness of our result.
