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

Abstract:

In this work we study a non-local version of the Fisher-KPP equation, (∂u ∂t = 1 2∆u + u(1 − φ ∗ u), t > 0, x ∈ R, u(0, x) = u0(x), x ∈ R and its relation to a branching Brownian motion with decay of mass as introduced in [1], i.e. a particle system consisting of a standard branching Brownian motion (BBM) with a competitive interaction between nearby particles. Particles in the BBM with decay of mass have a position in R and a mass, branch at rate 1 into two daughter particles of the same ...
