Rational curves on holomorphic symplectic fourfolds
Brendan Hassett, Yuri Tschinkel
Let F be a polarized irreducible holomorphic symplectic fourfold, deformation equivalent to the Hilbert scheme parametrizing length-two zero-dimensional subschemes of a K3 surface.…
Abelian fibrations and rational points on symmetric products
Brendan Hassett, Yuri Tschinkel
Given a variety over a number field, are its rational points potentially dense, i.e., does there exist a finite extension over which rational points are Zariski dense? We study the…
Brauer groups and quotient stacks
D. Edidin, B. Hassett, A. Kresch +1
A natural question is to determine which algebraic stacks are qoutient stacks. In this paper we give some partial answers and relate it to the old question of whether, for a scheme…
Geometry of equivariant compactifications of
Brendan Hassett, Yuri Tschinkel
Equivariant compactifications of reductive groups can be described by combinatorial data. On the other hand, equivariant compactifications of the additive group G^n_a are more comp…
