On projective varieties with nef anticanonical divisors
Qi Zhang
We prove a structure theorem for projective varieties with nef anticanonical divisors.
Rational connectedness of log -Fano varieties
Qi Zhang
In this paper, we give an affirmative answer to a conjecture in the Minimal Model Program. We prove that log -Fano varieties of dim are rationally connected. We also study t…
Holomorphic forms on threefolds
Tie Luo, Qi Zhang
Two conjectures relating the Kodaira dimension of a smooth projective variety and existence of number of nowhere vanishing 1-forms on the variety are proposed and verified in dimen…
On the geometry of the Hilbert schemes of points in the projective plane
Wei-ping Li, Zhenbo Qin, Qi Zhang
We classify minimal-degree curves in the Hilbert schemes of points on algebraic surfaces. When the algebraic surface is the projective plane, the nef cone and a flip structure of t…
