Anisotropic min-max via phase transitions
Antonio De Rosa, Alessandro Pigati
We develop a PDE-based approach to the min-max construction of nontrivial integer rectifiable varifolds that are stationary with respect to anisotropic surface energies on closed R…

A Variational Theory for The Area of Legendrian Surfaces
Alessandro Pigati, Tristan Rivière
We study a new notion of critical point for the area of surfaces under the Legendrian constraint, called parametrized Hamiltonian stationary Legendrian varifolds (PHSLVs). We estab…
