The one-dimensional equilibrium shape of a crystal
Emanuel Indrei
Optimizing the free energy under a mass constraint may generate a convex crystal subject to assumptions on the potential , . The general problem classically attrib…

The nonlocal Almgren problem
Emanuel Indrei
In the nonlocal Almgren problem, the goal is to investigate the convexity of a minimizer under a mass constraint via a nonlocal free energy generated with some nonlocal perimeter a…

On the three-dimensional shape of a crystal
Emanuel Indrei, Aram Karakhanyan
In this paper we completely settle the Almgren problem in under some generic conditions on the potential and tension functions. The problem, among other things, appea…
