Algebraization for zero-cycles and the $p$-adic cycle class map

Pages: 557 – 585

Using an idelic argument and assuming the Gersten conjecture for Milnor $K$-theory, we show that the restriction map from the Chow group of one-cycles on a smooth projective scheme over a henselian local ring to a pro-system of thickened zero-cycles is surjective. We relate this restriction map to the $p$-adic cycle class map.
