Non-Local Anisotropic Dispersal with Monostable Nonlinearity

Jerome Coville, Juan Davila and Salome Martinez

Abstract

We study the travelling wave problem $$ J\star u -u -cu^{\prime}+f(u)=0\quad{ in } \quad \mathbb{R}, \quad u(-\infty)=0, \quad u(+\infty)=1 $$ with an asymmetric kernel $J$ and a monostable nonlinearity. We prove the existence of a minimal speed, and under certain hypothesis the uniqueness of the profile for $c\not=0$. For $c=0$ we show examples of non-uniqueness.
