Some results about zero-cycles on abelian and semi-abelian varieties

Algebraic Geometry 2018-11-19 v2 Number Theory

Abstract

In this short note we extend some results obtained in \cite{Gazaki2015}. First, we prove that for an abelian variety AA with good ordinary reduction over a finite extension of Qp\mathbb{Q}_p with pp an odd prime, the Albanese kernel of AA is the direct sum of its maximal divisible subgroup and a torsion group. Second, for a semi-abelian variety GG over a perfect field kk, we construct a decreasing integral filtration {Fr}r0\{F^r\}_{r\geq 0} of Suslin's singular homology group, H0sing(G)H_0^{sing}(G), such that the successive quotients are isomorphic to a certain Somekawa K-group.
