Variational problems with soap films,
free boundaries and eggshells

Soap films tend to minimize their two-dimensional area with respect to constraints of the specific situation. For bubbles the enclosed volume is the constraint. Wire-constructions lead to fixed boundary conditions and produce soap films similar to the famous roof of the Munich Olympic Stadium. In mathematics soap films are considered as minimal surfaces or more generally as surfaces of consant mean curvature, if a volume constraint is imposed. We give a basic introduction to the mathematical theory ending up with a recent result for a problem with volume constraint and free boundary in an egg-shaped support.
