Rationality of singular cubic threefolds over
Ivan Cheltsov, Yuri Tschinkel, Zhijia Zhang
We study rationality properties of real singular cubic threefolds.
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.
Stable equivariant birationalities of cubic and degree 14 Fano threefolds
Yuri Tschinkel, Zhijia Zhang
We develop an equivariant version of the Pfaffian-Grassmannian correspondence and apply it to produce examples of nontrivial twisted equivariant stable birationalities between cubi…
Equivariant geometry of singular cubic threefolds, II
Ivan Cheltsov, Lisa Marquand, Yuri Tschinkel +1
We study linearizability of actions of finite groups on cubic threefolds with nonnodal isolated singularities.
Intermediate Jacobians and linearizability
Tudor Ciurca, Sho Tanimoto, Yuri Tschinkel
We develop an equivariant version of the formalism of intermediate Jacobian torsor obstructions, and apply it to conic bundles over rational surfaces, quadric surface bundles over…
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.
