摘    要:本文,我们研究了三维Minkowski空间R2.1中保持平均曲率函数不变的类空曲面和类时曲面的等距形变问题──称为H-形变问题.首先,对于H-可形变的类空浸入和类时浸入的存在性给出了一个充要条件.其次.讨论了具有常平均曲率的类空和类时曲面的H-形变.进一步,我们给出了H-可形变的类空和类时曲面的两个特征.最后,给出了一个平坦类时曲面H-形变的例子.

关 键 词:Minkowski空间,类空曲面,类时曲面,H-形空,特征

Abstract:In this peper, we stier the isonetric deformations of the sparelik. and timelike surfaces in 3dimensional Minkowski space R2.1 preserving the mean curvature function, which are, called H.deformation first, we give a necessary and sufficient .condition for the existence of the H-deformable spacelike or tirnelike immersion in R2.1, Next, we discuss the H-deformations of the spacelike and'timelik. surfaces with constant'mean curvature. Moreover,we offer twocharacterizations of the H-deformable spacelike or timelike surface in R2,1. At last, we give aexample of H-deformation of flat timelike surface.
Keywords:Minkowski space spacelike surface timelike surface H-deformation characterizafion
