Existence and qualitative properties of isoperimetric sets in periodic media
Antonin Chambolle, Michael D. Goldman, Matteo Novaga · Scuola Normale Superiore eBooks · 2013
We review and extend here some recent results on the existence of minimal surfaces and isoperimetric sets in non homogeneous and anisotropic periodic media. We also describe the qualitative properties of the homogenized surface tension, also known as stable norm (or minimal action) in Weak KAM theory. In particular we investigate its strict convexity and differentiability properties.
