Künneth Decompositions for Quotient Varieties
نویسنده
چکیده
In this paper we discuss Künneth decompositions for finite quotients of several classes of smooth projective varieties. The main result is the existence of an explicit (and readily computable) Chow-Künneth decomposition in the sense of Murre with several pleasant properties for finite quotients of abelian varieties. This applies in particular to symmetric products of abelian varieties and also to certain smooth quotients in positive characteristics which are known to be not abelian varieties, examples of which were considered by Enriques and Igusa. We also consider briefly a strong Künneth decomposition for finite quotients of projective smooth linear varieties.

Rationality and Chow–künneth Decompositions for Some Moduli Stacks of Curves
In this paper we show the existence of a Chow–Künneth decomposition for the moduli stack of stable curves with marked points Mg,r, for low values of g, r. We also look at the moduli space R3,2 of double covers of genus three curves, branched along 4 distinct points. We first obtain a birational model of R3,2 as a group quotient of a product of two Grassmannian varieties. This provides a Chow–Kü...
متن کاملChow–künneth Decomposition for Special Varieties
In this paper we investigate Murre’s conjecture on the Chow–Künneth decomposition for two classes of examples. We look at the universal families of smooth curves over spaces which dominate the moduli space Mg, in genus at most 8 and show existence of a Chow–Künneth decomposition. The second class of examples include the representation varieties of a finitely generated group with one relation. T...
متن کاملLefschetz Decompositions for Quotient Varieties
In an earlier paper, the authors constructed an explicit Chow Kunneth decomposition for quotient varieties of Abelian varieties by actions of finite groups. In the present paper, the authors extend the techniques there to obtain an explicit Lefschetz decomposition for such quotient varieties for the Chow-Kunneth projectors constructed there.
متن کاملRelative Chow-Künneth decompositions for conic bundles and Prym varieties
We construct a relative Chow-Künneth decomposition for a conic bundle over a surface such that the middle projector gives the Prym variety of the associated double covering of the discriminant of the conic bundle. This gives a refinement (up to an isogeny) of Beauville’s theorem on the relation between the intermediate Jacobian of the conic bundle and the Prym variety of the double covering.
