Steenrod operations on the Chow ring of a classifying space
نویسنده
چکیده
We use the Steenrod algebra to study the Chow ring CH∗BG of the classifying space of an algebraic group G. We describe a localization property which relates a given G to its elementary abelian subgroups, and we study a number of particular cases, namely symmetric groups and Chevalley groups. It turns out that the Chow rings of these groups are completely determined by the abelian subgroups and their fusion.

Extended Powers and Steenrod Operations in Algebraic Geometry
Steenrod operations were defined by Voedvodsky in motivic cohomology in order to prove the Milnor and Bloch-Kato conjectures. These operations have also been constructed by Brosnan for Chow rings [5]. The purpose of this paper is to provide a setting for the construction of the Steenrod operations in algebraic geometry, for generalized cohomology theories whose formal group law has order two. W...
متن کاملA note on the new basis in the mod 2 Steenrod algebra
The Mod $2$ Steenrod algebra is a Hopf algebra that consists of the primary cohomology operations, denoted by $Sq^n$, between the cohomology groups with $mathbb{Z}_2$ coefficients of any topological space. Regarding to its vector space structure over $mathbb{Z}_2$, it has many base systems and some of the base systems can also be restricted to its sub algebras. On the contrary, in ...
متن کاملThe Chow ring of the Classifying Space BSO(2n,C)
We compute the Chow ring of the classifying space BSO(2n, C) in the sense of Totaro using the fibration Gl(2n)/SO(2n) → BSO(2n) → BGl(2n) and a computation of the Chow ring of Gl(2n)/SO(2n) in a previous paper. We find this Chow ring is generated by Chern classes and a characteristic class defined by Edidin and Graham which maps to 2 times the Euler class under the usual class map from the Chow...
متن کاملInvariant elements in the dual Steenrod algebra
In this paper, we investigate the invariant elements of the dual mod $p$ Steenrod subalgebra ${mathcal{A}_p}^*$ under the conjugation map $chi$ and give bounds on the dimensions of $(chi-1)({mathcal{A}_p}^*)_d$, where $({mathcal{A}_p}^*)_d$ is the dimension of ${mathcal{A}_p}^*$ in degree $d$.
متن کاملHoles in I
Let F be a field with char(F ) 6= 2. We prove Vishik’s conjecture stating that for any positive integer n and any anisotropic quadratic form φ over F lying in the n-th power I of the fundamental ideal I of the Witt ring of F , either dim(φ) ≥ 2 or dim(φ) = 2 − 2 for some i ∈ {1, 2, . . . , n+ 1}. This provides a complete solution of an old-standing problem in the algebraic theory of quadratic f...
