A one-dimensional symmetry result for a class of nonlocal semilinear equations in the plane
Annales de l'I.H.P. Analyse non linéaire, Tome 34 (2017) no. 2, pp. 469-482.

We consider entire solutions to Lu=f(u) in R2, where L is a nonlocal operator with translation invariant, even and compactly supported kernel K. Under different assumptions on the operator L, we show that monotone solutions are necessarily one-dimensional. The proof is based on a Liouville type approach. A variational characterization of the stability notion is also given, extending our results in some cases to stable solutions.
