Front blocking in the presence of gradient drift

[摘要] This paper tries to understand how a drift influences the wave propagation of a bistable reaction-diffusion equation in straight cylinders in dimension n >= 3. We derive a quantitative condition under which a compactly supported drift term blocks the propagation of a traveling wave. We assume for this that the drift has a potential. (C) 2019 Elsevier Inc.
