Triple lines on a cubic threefold

Algebraic Geometry 2022-02-03 v2

Abstract

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.
