Branching Brownian motion with decay of mass and the non-local Fisher-KPP equation

Louigi Addario-Berry, Julien Berestycki, Sarah Penington

In this work we study a non-local version of the Fisher-KPP equation, \begin{equation*} \begin{cases} \frac{\partial u}{\partial t}=\tfrac{1}{2}Δu +u (1- ϕ\ast u), \quad t>0, \quad…

The spreading speed of solutions of the non-local Fisher-KPP equation

Sarah Penington

We consider the Fisher-KPP equation with a non-local interaction term. Hamel and Ryzhik showed that in solutions of this equation, the front location at a large time t is $\sqrt…
