2n Positive Periodic Solutions to n Species Non-autonomous Lotka-Volterra Competition Systems with Harvesting Terms
Authors: Yongkun Li, Kaihong Zhao
Abstract:
By using Mawhin-s continuation theorem of coincidence degree theory, we establish the existence of 2n positive periodic solutions for n species non-autonomous Lotka-Volterra competition systems with harvesting terms. An example is given to illustrate the effectiveness of our results.
Keywords: Positive periodic solutions, Lotka-Volterra competition system, coincidence degree, harvesting term.
