DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OSGA/7/">The
  Canham-Helfrich model for multiphase biomembranes</a>\nby Katharina Brazd
 a (University Vienna) as part of Online Seminar "Geometric Analysis"\n\n\n
 Abstract\nBiological membranes adopt a fascinating variety of shapes. The 
 Canham-Helfrich variational model describes their equilibrium configuratio
 ns as surfaces of minimal elastic bending energy under area and volume con
 straints. In case of heterogeneous membranes with multiple phases\, latera
 l fluidity gives rise to an additional coupling between composition and cu
 rvature. We present an existence result for multiphase Canham-Helfrich min
 imizers with sharp phase interfaces obtained in the framework of oriented 
 curvature varifolds with boundary. This is joint work with Luca Lussardi a
 nd Ulisse Stefanelli.\n
