Rescaling of diffusion coefficients in two-time scale chemical systems

Mostrar todas las versiones(3)

We study reaction-diffusion systems which involve processes that occur on different time scales. In particular, we apply a multiscale analysis to obtain a reduced description of the slow dynamics. Under certain assumptions this reduction yields a new set of reaction-diffusion equations with rescaled...
