Existence of multiple periodic solutions for delay Lotka-Volterra competition patch systems with harvesting. (English) Zbl 1168.34349

Summary: We establish some new and interesting sufficient conditions on the existence of multiple positive periodic solutions for a delay Lotka-Volterra competition patch system with harvesting. Our method is based on Mawhin’s coincidence degree and some novel techniques for defining the operator \(N(u,\lambda )\) and obtaining a priori bounds.
