Abstract

Abstract: In this paper, by using the Mawhin's continuation theorem of coincidence degree theory and differential inequality, the existence of at least four positive periodic solutions is established for a discrete non-autonomous plankton allelopathy system with harvesting terms. Moreover, an example is provided to illustrate the effectiveness of the proposed result.

Key words: discrete, non-autonomous, periodic solutions, plankton allelopathy system, harvesting terms
