Triple lines and Eckard points on a cubic threefold
The variety that parametrizes the lines on a smooth cubic threefold is a smooth surface of general type known as the Fano surface. Among these lines, those of the second type are of particular interest: their locus in the associated Fano surface is an algebraic curve whose study goes back to Murre’s work in 1972. In this talk, we will investigate the role of triple lines in the geometry of this curve and explore the relationships between these lines and Eckardt points.
