论文摘要
本文涉及在光滑的复杂立方三倍中包含的线条。众所周知,第二类三倍的第二类线的组集是其Fano表面上的曲线。在这里,我们对此曲线的奇异性进行描述。
The present paper deals with lines contained in a smooth complex cubic threefold. It is well-known that the set of lines of the second type on a cubic threefold is a curve on its Fano surface. Here we give a description of the singularities of this curve.
