From constant mean curvature hypersurfaces to the gradient theory of phase transitions

Frank Pacard & Manuel Ritoré

Abstract:

Given a nondegenerate minimal hypersurface $\Sigma$ in a Riemannian manifold, we prove that, for all $\varepsilon$ small enough there exists $u_\varepsilon$, a critical point of the Allen-Cahn energy $E_\e (u) = \varepsilon^2 \, \int |\nabla u|^2 + \int (1-u^2)^2$, whose nodal set converges to $\Sigma$ as $\varepsilon$ tends to $0$. Moreover, if $\Sigma$ is a volume nondegenerate constant mean curvature hypersurface, then the same conclusion holds with the function $u_\varepsilon$ being a critical point of $E_\e$ under some volume constraint.
