SUMMARY:Curvature Flows with Free Boundaries - Lee\, KA (Seoul National Un
 iversity)

CONTACT:Mustapha Amrani
DESCRIPTION:In this talk\, we are going to discuss alpha- Gauss Curvature 
 Flows with free boundaries. For a=1n\, a flat spot on convex manifold will
  persists for some time\, which is similar as the waiting time in Porous M
 edium Equations. Naturally\, the interface between strictly convex region 
 and flat spot will form a free boundary that will moves along the time. We
  will show the relation between optimal regularity and bounded nondegenera
 te speed of free boundaries. The optimal regularity and the smoothness of 
 the free boundary will be discussed. We will also consider the dynamics an
 d regularity of free boundary of the manifold with a concave region. \n
