On the Invariant Regions and Global Existence of Solutions for Four Components Reaction-Diffusion Systems With a Full Matrix of Diffusion Coefficients and Nonhomogeneous Boundary Conditions

In this work we consider a reaction-diffusion systems (four equations) with a full matrix of diffusion and with nonhomogeneous boundary conditions, by using the Invariant regions and Lyapunov functional method we established the global existence of solution.
