Existence and instability of deformed catenoidal solutions for fractional Allen--Cahn equation
arXiv:1711.03215
Abstract
We develop a new infinite dimensional gluing method for fractional elliptic equations. As a model problem, we construct solutions of the fractional Allen--Cahn equation vanishing on a rotationally symmetric surface which resembles a catenoid and have sub-linear growth at infinity. Moreover, such solutions are unstable.
This is a revised and expanded version of the previous article titled "A gluing construction for fractional elliptic equations. Part I: a model problem on the catenoid"
