These are the cooperating species model, the competing species model, and the predator-prey model. In this paper, we extend the cooperating species model and the competing species model to the study of human population dynamics.</p> Art Kazmierczak ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-nd/4.0 http://gphjournal.org/index.php/m/article/view/563 Thu, 17 Mar 2022 09:42:56 +0000
