DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OSGA/103/">C
 onvergence and metastability of (weakly) nonconvex gradient flows</a>\nby 
 Maria G. Westdickenberg (RWTH Aachen University) as part of Online Seminar
  "Geometric Analysis"\n\n\nAbstract\nTogether with Felix Otto\, Richard Sc
 hubert\, and other collaborators\, we have\ndeveloped two different energy
 -based methods to capture convergence and metastability. We have\nused the
 se methods to establish optimal\, algebraic convergence for the Mullins-Se
 kerka (MS)\nproblem in the plane and the Cahn-Hilliard equation on the lin
 e. After a general introduction of the central ideas\, we comment in parti
 cular on the role of curvature in the MS problem. Work in progress with Ri
 chard Schubert and Felix Otto extends the L1-based method to the Mullins-S
 ekerka evolution in three dimensions.\n
