三维曲线缩短流中的距离比较原理和Grayson型定理

Distance comparison principle and Grayson type theorem in the three dimensional curve shortening flow

Siming He

摘要:

本文利用G. Huisken,研究空间曲线缩短流。我们得到了当初始曲线为螺旋线时,内外距离之比的局部极小值不减的结果。并证明了各种空间曲线的一个Grayson型定理。

英文摘要:

In this paper, we use the distance comparison principle, first been developed by G. Huisken, to study the spatial curve shortening flow. We have got the result that if the initial curve is the helix, then the local minimum of the ratio of the extrinsic and intrinsic distance is non-decreasing. And we have proved a Grayson type theorem for a variety of spatial curves.
