摘要:In this talk, by using new auxiliary functions, we study a class of contracting flows of closed, star-shaped hypersurfaces in R^n+1 with speed $r^{\frac{\alpha}{\beta}} \sigma_k^{\frac{1}{\beta}}$, where $\sigma_k$ is the $k$-th elementary symmetric polynomial of the principal curvatures, $\alpha$, $\beta$ are positive constants and $r$ is the distance from points on the hypersurface to the origin. We generalize Li-Sheng-Wang's result from uniformly convex to $k$-convex and Ling Xiao's result from $k=2$ to $k \geq 2$. This is a joint work with Botong Xu and Ruijia Zhang.
