Periodic Solutions for Impulsive Differential Equations Model of Plankton Allelopathy
In this paper, we study a modified impulsive Lotka-Volterra competition model which involves interactions between two species of plankton having competitive and allelopathic effects on each other. The species grow in a periodically changing environment with instantaneous changes in the population densities.The mathematical model is described by a periodic impulsive differential equations. A monotone-iterative scheme is established for finding the periodic solution of the model, a set of easily verifiable sufficient conditions are obtained for the existence of at least one strictly positive periodic solution. Some computer simulations are carried out to demonstrate the main results.
