Abstract:
Using Mawhin's continuation theorem of coincidence degree
theory, we establish the existence of
positive
periodic solutions for a non-autonomous Lotka-Volterra
network-like predator-prey system with harvesting terms.
Here n and m denote the number of prey and predator species
respectively. An example is given to illustrate our results.
