Four positive periodic solutions of a discrete time Lotka-Volterra competitive system with harvesting terms
In this paper, by using Mawhin's continuation theorem of coincidence degree theory, we establish the existence of at least four positive periodic solutions for a discrete time Lotka-Volterra competitive system with harvesting terms. An example is given to illustrate the effectiveness of our res...
