Shock wavefronts for parabolic equations with sign-changing diffusivity
Existence of a family of discontinuous shock wavefronts is established for bistable reaction-diffusion equations with sign-changing diffusivity where the interior reaction zero lies in the negative region, together with their speeds and an application to a mixed individual-group population model.
