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

Abstract

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.
