DESCRIPTION:Speakers: Prof. BOBENKO\, Alexander (TU Berlin)\nWe consider a
  classical problem in differential geometry\, known as the Bonnet problem\
 , whether a surface is characterized by a metric and mean curvature functi
 on. We explicitly construct a pair of immersed tori that are related by a 
 mean curvature preserving isometry. This resolves a longstanding open prob
 lem on whether the metric and mean curvature function determine a unique c
 ompact surface. Discrete integrable systems and discrete differential geom
 etry are used to find crucial geometric properties of surfaces. This is a 
 joint work with Tim Hoffmann and Andrew Sageman-Furnas.\n\nhttp://indico.f
