Chow groups and tubular neighbourhoods
Journal of Singularities, 2010We will prove theorems of Zariski-Lefschetz type for the analytic Chow groups of a quasi-projective variety. We will also derive an algebraic analogue, using formal instead of tubular neighbourhoods.

DGA-Structure on Additive Higher Chow Groups
International Mathematics Research Notices, 2013Summary: We construct a graded-commutative differential graded algebra structure on additive higher Chow groups of a smooth projective variety over a perfect field. We show that these groups are equipped with Frobenius and Verschiebung operators that turn the collection into a Witt complex.

Equivariant Chow groups and multiplicities
2008We propose a definition of equivariant Chow groups for schemes with a torus action and develop the intersection theory related to it. The equivariant intersection theories that have been considered in the past have been the Chow groups and the K-theory of the quotient scheme, as well as the equivariant K-groups of the original scheme.

On the Chow Groups of Supersingular Varieties
Canadian Mathematical Bulletin, 2002AbstractWe compute the rational Chow groups of supersingular abelian varieties and some other related varieties, such as supersingular Fermat varieties and supersingular K3 surfaces. These computations are concordant with the conjectural relationship, for a smooth projective variety, between the structure of Chow groups and the coniveau filtration on ...

NORI’S CONNECTIVITY THEOREM AND HIGHER CHOW GROUPS
Journal of the Institute of Mathematics of Jussieu, 2002Let \(X\) be a smooth complex projective variety of dimension \(n+r\), and let \(L_1, \ldots, L_r\) be ample line bundles on \(X\). If \(B= \sum_i H^0 (X,L_i)\), then the connectivity theorem of \textit{M. V. Nori} [Invent. Math. 111, 349--373 (1993; Zbl 0822.14008)] compares the cohomology of \(X\times B\) and \(Y_B\), where \(Y_B\) is a locally ...

Regulators on Higher Chow Groups
2018There are two natural questions one can ask about the higher Chow group of number fields: One is its torsion, the other one is its relation with the homology of GLn. For the first question, based on some earlier work, the integral regulator on higher Chow complexes introduced here can put a lot of earlier result on a firm ground.
