Moitri Sen, Vitaly Volpert, Vitali Vougalter Existence of waves for a reaction-diffusion-dispersion system (146K, pdf) ABSTRACT. Existence of travelling waves is studied for a bistable reaction-diffusion system of equations with linear integral terms (dispersion) and with some conditions on the nonlinearity. The proof is based on the Leray-Schauder method using the topological degree theory for Fredholm and proper operators with the zero index and a priori estimates of solutions in properly chosen weighted spaces.
