Query: Minimizers for a fractional Allen-Cahn equation in a periodic medium   We aim to study the solutions of a fractional mesoscopic model of phase
transitions in a periodic medium. After investigating the geometric properties
of the interface of the associated minimal solutions, we construct minimal
interfaces lying to a strip of prescribed direction and universal width.
