| Research Abstract |
To classify the nonlinearities of reaction-diffusion systems, we studied the following researches. We derive the limit problem from some reaction-diffusion systems by using the fast reaction limit and discuss the relationship between the degeneracy of nonlinearity and the limit problem. We also constructed non-planar traveling waves of Allen-Cahn equations or the free boundary value problem which comes from some reaction-diffusion system, which are of finger type and of spot type. We also studied the imperfect bifurcation of some elliptic problem under the perturbation of the domain.
