Abstract: We discuss a recent work in progress on a class of in-homogeneous Gauss curvature flows. The Gauss curvature flow (GCF) was introduced by Firey in 1970s with the goal to understand the "shape of worn stones". GCF, together with flow by power of Gauss curvature have been extensively studied. These flows converge to solitons by works of Andrews, Guan-Ni and Andrews-Guan-Ni. The uniqueness of solitons was proved by Brendle-Choi-Daskalopoulous. In the talk, we present convergence result for a class of in-homogeneous Gauss curvature flows. Main step is to establish almost monotonicity for an associated entropy to flow. Adopting arguments for GCF, the entropy estimate yields non-collapsing estimate and the convergence of flow to exactly the same soliton as for flow by power of Gauss curvature.
