Abstract:
In this talk, I will talk about something about the propagation speed in monostable fractional reaction-diffusion equation. More precisely, by constructing some super and subsolution, for the generalized Fisher-KPP model, we can obtain an optimal upper bound(optimal is critical line for the existence of the plane traveling wave) and a very rough lower bound for the propagation asymptotic behavior. As a consequence, we can get the optimal upper and lower bound for the combustion model in the supercritical fractional Laplcian case. This is a joint work with Professor Jerome Coville and Professor Changfeng Gui .
