Title: The Willmore Flow in Riemannian Spaces

Abstract: in this talk I will detail recent developments 
on the Willmore flow of surfaces in 3-manifolds with a 
prescribed Riemannian structure. If this structure is 
flat then local parabolic regularity for data in terms 
of the local L^2-norm of the second fundamental form is 
contained in Kuwert and Schaetzle’s previous work on the 
Willmore functional. If there is some ambient curvature 
then several problems arise: the evolution of key 
geometric quantities becomes more complex and tools such 
as the Sobolev inequality are either invalid or hold only 
in special circumstances. Using a new concentration of 
area method we are able to recover an analogue of Kuwert 
and Schaetzle’s local parabolic regularity theorem. We 
present one application yielding a global existence 
result in certain ambient spaces. This is joint work 
with Jan Metzger and Valentina-Mira Wheeler.
