Chow Groups, Chow Cohomology, and Linear Varieties
We compute the Chow groups and Fulton–MacPherson’s operational Chow cohomology ring for a class of singular rational varieties including toric varieties. The computation is closely related to the weight filtration on the ordinary cohomology of these varieties. We use the computation to answer one of the open problems about operational Chow cohomology: it does not have a natural map to ordinary ...
متن کاملEquivariant Chow cohomology of toric varieties
We show that the equivariant Chow cohomology ring of a toric variety is naturally isomorphic to the ring of integral piecewise polynomial functions on the associated fan. This gives a large class of singular spaces for which localization holds in equivariant Chow cohomology with integer coefficients. We also compute the equivariant Chow cohomology of toric prevarieties and general complex hyper...
متن کاملEquivariant Chow Cohomology of Nonsimplicial Toric Varieties
Abstract. For a toric variety XΣ determined by a polyhedral fan Σ ⊆ N , Payne shows that the equivariant Chow cohomology is the Sym(N)–algebra C(Σ) of integral piecewise polynomial functions on Σ. We use the CartanEilenberg spectral sequence to analyze the associated reflexive sheaf C(Σ) on PQ(N), showing that the Chern classes depend on subtle geometry of Σ and giving criteria for the splittin...
متن کاملHigher Chow Groups and Etale Cohomology
The main purpose of the present paper is to relate the higher Chow groups of varieties over an algebraically closed field introduced by S.Bloch [B1] to etale cohomology. We follow the approach suggested by the auther in 1987 during the Lumini conference on algebraic K-theory. The first and most important step in this direction was done in [SV1], where singular cohomology of any qfh-sheaf were c...
متن کاملHomology Using Chow Varieties
We introduce "Lawson homology groups" LrH2r+i(Xf2i) associated to an arbitrary projective algebraic variety X over an algebraically closed field k of characteristic p > 0 and a prime I ^ p. Our work is directly inspired by recent work of Blaine Lawson (cf. [5, 6]), consisting in part of an algebraization of Lawson's geometric ideas and analytic arguments. The Lawson homology group LQH^X, Z/) is...
