Long-range phase coexistence models: recent progress on the fractional Allen-Cahn equation (1803.03850v3)

Published 10 Mar 2018 in math.AP

Abstract: In this set of notes, we present some recent developments on the fractional Allen-Cahn equation $$ (-\Delta)^s u = u-u^3,$$ with special attention to $\Gamma$-convergence results, energy and density estimates, convergence of level sets, Hamiltonian estimates, rigidity and symmetry results.
