On approximate solutions to the wavefront speed of reaction-diffusion-convection problem in nonuniform media

摘要

A class of perturbed reaction-diffusion-convection (R-D-C) equations with reaction, diffusion and convection functions in nonuniform media is studied. By using singular perturbation analysis and Hamilton-Jacobi theory, the wavefront speed of such R-D-C equations is computed for different classes of nonlinearities.
