Description

We characterize boundary regularity for a specific variational soap film model. 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 [2], for a planar curve as the midline of the tubular neighborhood, we show that minimizers are normal smooth graphs with constant mean curvature constructed over the plane and forming on the tubular neighborhood a contact angle equal to $\pi/2$.
