Periodic KPP equations: new insights into persistence, spreading, and the role of advection

Nathanaël Boutillon, François Hamel, Lionel Roques

We focus on the persistence and spreading properties for a heterogeneous Fisher-KPP equation with advection. After reviewing the different notions of persistence and spreading spee…

Impact of diffusion mechanisms on persistence and spreading

Nathanaël Boutillon, Yong-Jung Kim, Lionel Roques

We examine a generalized KPP equation with a ``-diffusion", which is a framework that unifies various standard linear diffusion regimes: Fickian diffusion (), Stratonovic…
