Cubic fourfolds of discriminant 24 and rationality

Brendan Hassett

Cubic fourfolds of discriminant 24 contain special codimension-two algebraic cycles of degree 6 and self-intersection 20. Such cycles may be represented by singular scrolls or del…

Equivariant geometry of low-dimensional quadrics

Brendan Hassett, Yuri Tschinkel

We provide new stable linearizability constructions for regular actions of finite groups on homogeneous spaces and low-dimensional quadrics.

Rationality of forms of

Brendan Hassett, Yuri Tschinkel, Zhijia Zhang

We study equivariant geometry and rationality of moduli spaces of points on the projective line, for twists associated with permutations of the points.
