Abstract:We exhibit new examples of rational cubic fourfolds, parametrized by a countably infinite union of codimen\-sion-two subvarieties in the moduli space. Our examples are fibered in sextic del Pezzo surfaces over the projective plane; they are rational whenever the fibration has a rational section. 
Rational cubic fourfolds in Hassett divisors
We prove that every Hassett's Noether-Lefschetz divisor of special cubic fourfolds contains a union of three codimension-two subvarieties, parametrizing rational cubic fourfolds, in the moduli spaceExpand

New rational cubic fourfolds arising from Cremona transformations
Are Fourier--Mukai equivalent cubic fourfolds birationally equivalent? We obtain an affirmative answer to this question for very general cubic fourfolds of discriminant 20, where we produceExpand
Hilbert schemes of two points on K3 surfaces and certain rational cubic fourfolds
Abstract In this article, we check that Fano schemes of lines on certain rational cubic fourfolds are birational to Hilbert schemes of two points on K3 surfaces.
Representability of Chow groups of codimension three cycles
Abstract Assume that we have a fibration of smooth projective varieties X → S over a surface S such that X is of dimension four and that the geometric generic fiber has finite-dimensional motive andExpand
A remark on algebraic cycles on cubic fourfolds
In this short note we try to generalize the Clemens-Griffiths criterion of non-rationality for smooth cubic threefolds to the case of smooth cubic fourfolds.
Refinement of the classification of weak Fano threefolds with sextic del Pezzo fibrations
We refine the classification of weak Fano threefolds with sextic del Pezzo fibrations by considering the Hodge numbers of them. By the refined classification result, such threefolds are classifiedExpand
Rational cubic fourfolds with associated singular K3 surfaces
Generalizing a recent construction of Yang and Yu, we study to what extent one can intersect Hassett's Noether-Lefschetz divisors $\mathcal{C}_d$ in the moduli space of cubic fourfolds $\mathcal{C}$.Expand
On lattice polarizable cubic fourfolds
We extend non-emtpyness and irreducibility of Hassett divisors to the moduli spaces of M -polarizable cubic fourfolds for higher rank lattices M , which in turn provides a systematic approach forExpand
Relative linear extensions of sextic del Pezzo fibrations over curves
We show that every sextic del Pezzo fibration over a curve (with a smooth total space and relative Picard rank one) is a relative linear section of a Mori fiber space with the general fiberExpand


Cubic Fourfolds, K3 Surfaces, and Rationality Questions

Del Pezzo Surfaces of degree 6 over an arbitrary field
We give a characterization of all del Pezzo surfaces of degree 6 over an arbitrary field $F$. A surface is determined by a pair of separable algebras. These algebras are used to compute the QuillenExpand
Primitive contractions of Calabi–Yau threefolds II
We construct several new examples of Calabi�Yau threefolds with Picard group of rank 1. Each of these examples is obtained by smoothing the image of a primitive contraction with exceptional divisorExpand

Hodge theory and derived categories of cubic fourfolds
Cubic fourfolds behave in many ways like K3 surfaces. Certain cubics - conjecturally, the ones that are rational - have specific K3s associated to them geometrically. Hassett has studied cubics withExpand
Some remarks on Brauer groups of K3 surfaces
Abstract We discuss the geometry of the genus one fibrations associated to an elliptic fibration on a K3 surface. We show that the two-torsion subgroup of the Brauer group of a general ellipticExpand

Brauer Groups on K3 Surfaces and Arithmetic Applications

A coregular space is a representation of an algebraic group for which the ring of polynomial invariants is free. In this paper, we show that the orbits of many coregular irreducible representationsExpand
