    Let X be a product of smooth projective curves over a finite unramified extension k of Qp. Suppose that the Albanese variety of X has good reduction and that X has a k-rational point. We propose the following conjecture. The kernel of the Albanese map CH(X) → Alb X(k) is p-divisible. When p is an odd prime, we prove this conjecture for a large family of products of elliptic curves and certain principal homogeneous spaces of abelian varieties. Using this, we provide some evidence for a local-to-global conjecture for zero-cycles of Colliot-Thélène and Sansuc (Duke Math J 48(2):421–447, 1981), and Kato and Saito (Contemporary Mathematics, vol. 55:255–331, 1986).

  • Galois symbol maps for abelian varieties over a p-adic field Reviewed International journal

    We study the Galois symbol map associated to the multiplicative group and an abelian variety which has good ordinary reduction over a p-adic field. As a byproduct, one can calculate the “class group” in the sense of the class field theory for curves over a p-adic field.

  • Divisibility and torsion in higher Chow groups over arithmetic fields Invited

    In this talk, I will discuss higher Chow groups over arithmetic fields, with emphasis on divisibility and torsion. For a projective smooth variety X of dimension d over a finite field, a local field, or a global field, I will explain structural results for the
    groups CH^{d+i}(X, j). These groups are shown to be l-divisible or uniquely l-divisible in
    ranges controlled by the l-cohomological dimension of the base field. I will then discuss the
    case where X is a curve over a global field and i = 1. Bloch's exact sequence relates the
    higher Chow group CH^2(X,1) to local terms and to the abelian geometric fundamental group. For elliptic curves E over number fields, this gives a description of CH^2(E,1) in terms of the mod p Galois representation on E[p]. This is joint work with Rin Sugiyama.
