Intermediate Jacobians and Burnside invariants
Andrew Kresch, Sho Tanimoto, Yuri Tschinkel
We propose new invariants in equivariant birational geometry, combining equivariant intermediate Jacobians and the Burnside formalism, for smooth rationally connected threefolds wi…
Equivariant unirationality of tori in small dimensions
Yuri Tschinkel, Zhijia Zhang
We study equivariant unirationality of actions of finite groups on tori of small dimensions.
Homological stability and weak approximation
Sho Tanimoto, Yuri Tschinkel
We investigate homological stability for the space of sections of Fano fibrations over curves in the context of weak approximation, and establish it for projective bundles, as well…
Conjugacy classes of linear actions in the plane Cremona group
Ivan Cheltsov, Yuri Tschinkel, Zhijia Zhang
We classify regular generically free actions of finite groups on the projective plane, up to conjugation in the Cremona group.
Equivariant unirationality of toric varieties
Andrew Kresch, Yuri Tschinkel
We introduce a torsor-theoretic obstruction to equivariant unirationality and show that it is also sufficient for actions of finite groups on toric varieties arising from automorph…
Equivariant geometry of cubic threefolds with non-isolated singularities
Ivan Cheltsov, Lisa Marquand, Yuri Tschinkel +1
We study linearizability of actions of finite groups on cubic threefolds with non-isolated singularities.
