Cycles of Codimension 3 on a Projective Quadric
نویسنده
چکیده
Let X be a nonsingular quadratic hypersurface in a projective space over an arb#rary field (of characteristic not two) and let CHPX be a Chow group of codimension p, that is, a group of classes of codimension p cycles on X with respect to rational equivalency. It is proved that torsion in CH 3X is either trivial or is a second order group. Torsion in CHPX, when p ~ 3, was studied earlier in RZhMat 1990, 9 A334 and 10 A389.

Codimension 2 Cycles on Products of Projective Homogeneous Surfaces
In the present paper, we provide general bounds for the torsion in the codimension 2 Chow groups of the products of projective homogeneous surfaces. In particular, we determine the torsion for the product of four Pfister quadric surfaces and the maximal torsion for the product of three Severi-Brauer surfaces. We also find an upper bound for the torsion of the product of three quadric surfaces w...
متن کاملON THE k-REGULARITY OF SOME PROJECTIVE MANIFOLDS
The conjecture on the (degree − codimension+ 1)regularity of projective varieties is proved for smooth linearly normal polarized varieties (X, L) with L very ample, for low values of ∆(X, L) = degree− codimension− 1. Results concerning the projective normality of some classes of special varieties including scrolls over curves of genus 2 and quadric fibrations over elliptic curves, are proved.
متن کاملLiaison Addition and the Structure of a Gorenstein Liaison Class
We study the concept of liaison addition for codimension two subschemes of an arithmetically Gorenstein projective scheme. We show how it relates to liaison and biliaison classes of subschemes and use it to investigate the structure of Gorenstein liaison equivalence classes, extending the known theory for complete intersection liaison of codimension two subschemes. In particular, we show that o...
متن کاملA Noether-lefschetz Theorem and Applications
In this paper we generalize the classical Noether-Lefschetz Theorem (see [7], [5]) to arbitrary smooth projective threefolds. More specifically, we prove that given any smooth projective threefold X over complex numbers and a very ample line bundle L on X, there is an integer n0(X,L) such that if n ≥ n0(X,L) then the Noether-Lefschetz locus of the linear system H(X,L) is a countable union of pr...
متن کاملRepresentability of Algebraic CHOW Groups of Complex Projective
Let X ⊂ Pn+r be an n dimensional smooth complex projective complete intersection of type (d1, . . . , dr). CHr(X) denotes the Chow group of codimension r algebraic cycles on X modulo rational equivalence and Ar(X) denotes the subgroup of the codimension r algebraic cycles that are algebraically equivalent to zero. In 1990 James D. Lewis made a conjecture on the representability of Ar(X). We wil...
