一类曲率流发展的渐近状态

Asymptotic behavior for one kind curvature flow

超曲面沿其法向分量按平均曲率大小的形变,已经得到了许多结论;在此基础上,考虑了超曲面沿其法向分量按平均曲率减去〈γ′(t),v〉大小的形变,得到了两个平行结论.

The evolution of hypersurface moving by the mean curvature was studied,and many conclusions were obtained,and on the basis of thse conclusions,the evolution of hypersurface moving by the mean curvature minused an external force field,two paralled conclusions were gotten.
