Abstract


In this paper, the obesity and tumor model with cancer stem cells has been analyzed. We aim to show that all solutions of the model are non-negative and bounded. Next, we find all equilibria of the models. We also investigate the conditions for the existence of positive equilibria for the model. Next, the local of the positive equilibrium is determined by the linearization method. Finally, we illustrate the numerical results using some advantages of mathematical software to support the analytic results and show the effect of some parameters for the model.
