Abstract

We consider the non-local Fisher-KPP equation on a bounded domain with\nNeu-mann boundary conditions. Thanks to a Lyapunov function, we prove that\nunder a general hypothesis on the Kernel involved in the non-local term, the\nhomogenous steady state 1 is globally asymptotically stable. This assumption\nhappens to be linked to some conditions given in the literature, which ensure\nthat travelling waves link 0 to 1.\n
