  • This paper addresses saddle-shaped solutions to the semilinear equation LKu=f(u) in R2m, where LK is a linear elliptic integro-differential operator with a radially symmetric kernel K, and f is of Allen-Cahn type. Saddle-shaped solutions are doubly radial, odd with respect to the Simons cone {(x′,x″)∈Rm×Rm:|x′|=|x″|}, and vanish only in this set. We establish the uniqueness and the asymptotic behavior of the saddle-shaped solution. For this, we prove a Liouville type result, the one-dimensional symmetry of positive solutions to semilinear problems in a half-space, and maximum principles in "narrow" sets. The existence of the solution was already proved in part Ⅰ of this work.
