Abstract
Joint work with Salvatore Stuvard (UNIMI) and Bozhidar Velichkov (UNIPI).
We characterize boundary regularity for a variational model of soap film spanning a tubular neighborhood of a curve. Inspired by [1], soap films are chosen to be sets of finite perimeter containing a fixed volume and satisfying a topological spanning condition. In this talk, for a planar curve as midline of a tubular neighborhood, we show that minimizers are normal smooth graphs with constant mean curvature constructed over the plane and forming a contact angle equal to π/2 [2].
