模环上的Suslin同调及其应用
Suslin homology via cycles with modulus and applications
摘要:
证明了对于域$k$上的光滑投射簇$X$和约化的有效Cartier因子$D \subset X$,在$k$和$D$上的某些必要条件下,模为$\mathrm{CH}_0(X|D)$的0-圈Chow群与Suslin同调$H^S_0(X \setminus D)$重合.我们得出几个后果,我们回答一个问题的Barbieri-Viale和卡恩。
英文摘要:
We show that for a smooth projective variety $X$ over a field $k$ and a reduced effective Cartier divisor $D \subset X$, the Chow group of 0-cycles with modulus $\mathrm{CH}_0(X|D)$ coincides with the Suslin homology $H^S_0(X \setminus D)$ under some necessary conditions on $k$ and $D$. We derive several consequences, and we answer to a question of Barbieri-Viale and Kahn.
