【摘要】:本文主要研究了四維Minkowski空間中偽零曲線的零超曲面的奇點分類問題.本文通過構造Frenet型標架和偽零曲線上的Lorentz距離平方函數(shù)族,利用奇點理論和函數(shù)開折理論討論了零超曲面的奇點和距離平方函數(shù)族的關系,給出零超曲面的奇點分類.此外,本文還給出了零超曲面的奇點的幾何性質.
[Abstract]:In this paper, we mainly study the singularity classification of zero hypersurfaces of pseudo-zero curves in four-dimensional Minkowski space. In this paper, by constructing the family of Lorentz distance square functions on Frenet frame and pseudo-zero curve, the relationship between singularity and distance square function family of zero hypersurfaces is discussed by using singularity theory and function opening theory, and the classification of singularity points of zero hypersurfaces is given. In addition, the geometric properties of singularity of zero hypersurface are also given in this paper.
