卡诺群中图的水平高斯曲率流

Horizontal Gauss Curvature Flow of Graphs in Carnot Groups

Erin Haller Martin

摘要:

本文证明了在Carnot群G × R中描述图的流的方程根据其水平Gauss曲率存在连续的黏性解.在此基础上,我们证明了一类退化抛物型方程u_t + F(D_0u,(D_0^2u)^*)= 0的比较原理,其中u定义在G上.

英文摘要:

We show the existence of continuous viscosity solutions to the equation describing the flow of a graph in the Carnot group G x R according to its horizontal Gauss curvature. In doing so, we prove a comparison principle for degenerate parabolic equations of the form u_t + F(D_0u, (D_0^2u)^*) = 0 for u defined on G.
