Christian Scharrer


I'm interested in geometric variational problems with motivations coming from physics and biology as well as in curvature based inequalities that arise in the context of such problems. More precisely, I've been working on the following topics

  • Constant mean curvature surfaces of revolution
  • Willmore energy under fixed isoperimetric ratio
  • Bending energies associated to biological cell membranes
  • Diameter bounds for solutions of Plateau's problem
  • Geometric inequalities in varifold geometry
