Abstract
We provide some explicit examples of nonlocal s-minimal surfaces for 0<s<1, namely
stationary for the s-perimeter functional, introduced first in the form
of a singular integral, related to fractional Laplacian, by
Caffarelli, Roquejoffre and Savin, which recovers the classical concept in the limit s-->1.
We find and analyze stability of a class of Lawson cones
which shows important differences with the classical case. In addition we construct
an axially symmetric analog of the catenoid in R3 in the limiting case when s approaches 1.
