Abstract:A class of new nonlinear singularly perturbed Robin initial boundary value problems for reaction diffusion systems of two-species competition are considered.Under suitable assumptions,the formal asymptotic expansion for these problems is constructed using the stretched variable.And the uniform validity of the solution for initial boundary value problems is proved using the theory of differential inequalities.
Keywords:nonlinear  two-species competitive system  reaction diffusion  singular perturbation  Robin problem
