On the stability of the state 1 in the non-local Fisher–KPP equation in bounded domains
Camille Pouchol · Comptes Rendus Mathématique · 2018
We consider the non-local Fisher–KPP equation on a bounded domain with Neumann boundary conditions. Thanks to a Lyapunov function, we prove that, under a general hypothesis on the kernel involved in the non-local term, the homogenous steady state 1 is globally asymptotically stable. This assumption happens to be linked to some conditions given in the literature, which ensure that travelling waves link 0 to 1.
