Geometric Analysis Seminar

## Free boundary problems on the Gauss curvature flow

#### Kyeongsu Choi: Columbia University

Location:  Hill 705
Date & time: Tuesday, 14 February 2017 at 3:00PM - 3:11PM

We will discuss about the optimal $C^{1,frac{1}{n-1}}$regularity of the Gauss curvature flow with a flat side and the $C^{infty}$regularity of its free boundary, namely the boundary of the flat side. We establish estimates by applying the maximum principle for chart independent geometric quantities.
