Algebraic Cycles and Intersections of 2 Quadrics
نویسندگان
چکیده
A smooth intersection Y of two quadrics in $$\mathbb {P}^{2g+1}$$ has Hodge level 1. We show that such varieties have a multiplicative Chow–Künneth decomposition, the sense Shen–Vial. As consequence, certain tautological subring Chow ring powers injects into cohomology.

Parameterizing Intersections of Time-Varying Quadrics
This report addresses the problem of computing the parametrization of the intersection of deformable quadratic algebraic surfaces (quadrics) in projective space. It also presents an automatic method for describing the evolution in time of the topology of the intersection. The work is based on the results from [3, 4], which offer an exact parametrization of the intersection of two quadrics with ...
متن کاملRational Points on Singular Intersections of Quadrics
— Given an intersection of two quadrics X ⊂ Pm−1, with m > 9, the quantitative arithmetic of the set X(Q) is investigated under the assumption that the singular locus of X consists of a pair of conjugate singular points defined over Q(i).
متن کاملCycles on Powers of Quadrics
These are notes of a part of my lectures on [3] given in the Universität Göttingen during the first week of November 2003. For a projective quadric X, some relative cellular structures on the powers of X are described and, as a consequence, a computation of the Chow groups of powers of X in terms of the Chow groups of powers of the anisotropic part of X, used in [3], is obtained, and this witho...
متن کاملDerived Categories of Quadric Fibrations and Intersections of Quadrics
We construct a semiorthogonal decomposition of the derived category of coherent sheaves on a quadric fibration consisting of several copies of the derived category of the base of the fibration and the derived category of coherent sheaves of modules over the sheaf of even parts of the Clifford algebras on the base corresponding to this quadric fibration generalizing the Kapranov’s description of...
متن کاملClassification of Free Actions on Complete Intersections of Four Quadrics
In this paper we classify all free actions of finite groups on Calabi-Yau complete intersection of 4 quadrics in P, up to projective equivalence. We get some examples of smooth CalabiYau threefolds with large nonabelian fundamental groups. We also observe the relation between some of these examples and moduli of polarized abelian surfaces.
