Abstract
In this paper, we construct a counterexample to the Liouville property of some nonlocal reaction-diffusion equations of the form
where is a bounded compact set, called an “obstacle”, and is a bistable nonlinearity. When is convex, it is known that solutions ranging in and satisfying as must be identically 1 in the whole space. We construct a nontrivial family of simply connected (non-starshaped) obstacles as well as data and for which this property fails.
