Abstract

The purpose of this paper is the construction of invariant regions in which we establish the global existence of solutions for reaction-diffusion systems three equations with a tridiagonal matrix of diffusion coefficients and with nonhomogeneous boundary conditions after the work of Kouachi 2004 on the system of reaction diffusion with a full 2-square matrix. Our techniques are based on invariant regions and Lyapunovfunctional methods. The nonlinear reaction term has been supposed to be ofpolynomial growth.
