A restriction isomorphism for cycles of relative dimension zero

Algebraic Geometry 2019-11-21 v2

Abstract

We study the restriction map to the closed fiber of a regular projective scheme over an excellent henselian discrete valuation ring, for a cohomological version of the Chow group of relative zero-cycles. Our main result extends the work of Saito--Sato to general perfect residue fields.
