Abstract:In this paper we are going to estimate domain of attraction of tumor-free equilibrium points in a perturbed cancer tumor model which is describing the tumor-immune system competition dynamics. The proposed method is based on solving an optimization problem for a chosen Lyapunov function that can be casted in terms of Linear Matrix Inequalities constraint and Taylor expansion of nonlinear terms. We will find a specific Lyapunov function in order to vanishing maximum perturbation of modeling error, aging or unce… Show more
