Alessandro Pigati (Università Bocconi): <b><a href='/seminar/984/'>Anisotropic Allen-Cahn and convergence to anisotropic area</a></b><br />
, 11:00<br />
</p>
<div style="font-size: smaller;"><p>In this talk we will introduce a PDE way to construct hypersurfaces which are critical for a generalization of area, based on an anisotropic integrand. Namely, we study energy concentration for rescalings of an anisotropic version of Allen-Cahn.
</p>
<p>After reviewing known existence and regularity results for minimizers and min-max solutions, as well as the Allen-Cahn approximation in the isotropic case, we will sketch a proof of the fact that energy of stable critical points (of the rescaled Allen-Cahn functional) concentrates along an integer rectifiable varifold, a weak notion of hypersurface, using stability (or finite Morse index) to compensate for the lack of monotonicity formulas.
</p>
<p>Among the technical ingredients, we will see a generalization of Modica's bound and a diffuse version of the stability inequality for hypersurfaces.
</p>
<p>This is joint work with Antonio De Rosa (Bocconi University).</p>
