Global existence for a free boundary problem of Fisher-KPP type
Julien Berestycki, Eric Brunet, Sarah Penington
Motivated by the study of branching particle systems with selection, we establish global existence for the solution of the free boundary problem \[ \begin{cases} \partial_t…

A new approach to computing the asymptotics of the position of Fisher-KPP fronts
Julien Berestycki, Éric Brunet, Bernard Derrida
This paper presents a novel way of computing front positions in Fisher-KPP equations. Our method is based on an exact relation between the Laplace transform of the initial conditio…
