本文证明了单位球面上严格单调、1-齐次、凸曲率函数f,0 <p\leq 1.如果f是平均曲率,我们得到了更强的Harnack不等式.
We prove Harnack inequalities for hypersurfaces flowing on the unit sphere by $p$-powers of a strictly monotone, 1-homogeneous, convex, curvature function $f$, $0<p\leq 1.$ If $f$ is the mean curvature, we obtain stronger Harnack inequalities.
