Extension of the Topological Abel-Jacobi Map for Cubic Threefolds
Yilong Zhang
The difference of a pair of skew lines on a cubic threefold defines a vanishing cycle on the cubic surface as the hyperplane section spanned by the two lines. By defo…

Hilbert Scheme of a Pair of Skew Lines on Cubic Threefolds
Yilong Zhang
A pair of disjoint lines on a smooth cubic threefold determines an irreducible component of the Hilbert scheme. We prove that this component is smooth and isomorphic to the blow-up…
