摘要:The Gauss curvature flow is an evolution of a convex hypersurface by its Gauss curvature which describes the shape of worn stones.

It has been widely studied not only in Geometry but also in Analysis, because it is a natural parabolic Monge-Amp\`ere equation. We will study its inverse concavity, divergence structure, and non-degenerate ellipticity to obtain monotonicity formulas and interior regularity.

We will also investigate free boundary problems and their application to the classification of the closed self-similar solutions.
