%0 Journal Article %T A restriction isomorphism for cycles of relative dimension zero %A Moritz Kerz %A H¨¦l¨¨ne Esnault %A Olivier Wittenberg %J Mathematics %D 2015 %I arXiv %X 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. %U http://arxiv.org/abs/1503.08187v1
