چکیده

Consider the formal power series P [Cp,α(X)]t α (called Motivic Chow Series), where Cp(X) = ∐Cp,α(X) is the Chow variety of X parametrizing the p-dimensional effective cycles on X with Cp,α(X) its connected components, and [Cp,α(X)] its class in K(ChM)A1 , the K-ring of Chow motives modulo A homotopy. Using Picard product formula and Torus action, we will show that the Motivic Chow Series is rational in many cases.

Irrationality of Motivic Series of Chow Varieties

The Euler characteristic of all the Chow varieties, of a fixed projective variety, can be collected in a formal power series called the Euler-Chow series. This series coincides with the Hilbert series when the Picard group is a finite generated free abelian group. It is an interesting open problem to find for which varieties this series is rational. A few cases have been computed, and it is sus...

An Overview of Motivic Cohomology

In this talk we give an overview of some of the motivations behind and applications of motivic cohomology.We first present aK-theoretic timeline converging onmotivic cohomology, then briefly discuss algebraic K-theory and its more concrete cousin Milnor K-theory. We then present a geometric definition of motivic cohomology via Bloch’s higher Chow groups and outline the main features of motivic ...

The Motivic Dga

The main goal of this paper is to associate to each smooth quasi-projective scheme X over any field an E∞ differential graded algebra whose cohomology groups are the higher Chow groups of X. Modulo torsion, this provides a strictly commutative differential graded algebra. Such a construction is currently known only for the case X itself is a field. Needless to say there are several applications...

Chow Quotients and Projective Bundle Formulas for Euler-chow Series

Given a projective algebraic variety X, let Πp(X) denote the monoid of effective algebraic equivalence classes of effective algebraic cycles on X. The p-th Euler-Chow series of X is an element in the formal monoid-ring Z[[Πp(X)]] defined in terms of Euler characteristics of the Chow varieties Cp,α (X) of X, with α ∈ Πp(X). We provide a systematic treatment of such series, and give projective bu...

Equivariant Motivic Cohomology

The present paper will form part of the author’s PhD thesis, which will concern in part the practical computation of the motivic cohomology and the equivariant motivic cohomology of homogeneous varieties, such as Stiefel manifolds, Grassmanians, and spaces of matrices with prescribed rank conditions. Nothing proved here is particularly surprising, but it seems to the author that the spectral se...
