Abstract

We obtain the bifurcation of some special curves on generic 1-parameter families of surfaces in the Minkowski 3-space. The curves treated here are the locus of points where the induced pseudo metric is degenerate, the discriminant of the lines principal curvature, the parabolic curve and the locus of points where the mean curvature vanishes.

闵科夫斯基三维空间曲面上稳健特征的分岔

我们得到了闵科夫斯基三维空间中一般一参数曲面族上一些特殊曲线的分岔。这里处理的曲线包括诱导伪度量退化的点的位置、直线主曲率的判别式、抛物曲线和平均曲率消失的点的位置。
