摘要

让 $k$ 是正特征 $p$ 的域,而 $X$ 是维数为 $d$ 的分离无穷型 $k$ 方案。我们构建了一个从加法循环复数到塞尔-格罗thendieck 相干性理论残差复数的循环映射。当$k$为完美时,这个映射与[Ren23] arXiv:2104.09662中构建的映射的立方体版本是兼容的。作为推论,当 $k$ 是代数闭合的时候,我们得到了(可加的)高周群的注入性声明,以及具有 $\mathbb{Z}/p$ 系数的形式同调(带模)。

Additive cycle complex and coherent duality
Let $k$ be a field of positive characteristic $p$, and $X$ be a separated of finite type $k$-scheme of dimension $d$. We construct a cycle map from the additive cycle complex to the residual complex of Serre-Grothendieck coherent duality theory. This map is compatible with a cubical version of the map constructed in [Ren23] arXiv:2104.09662 when $k$ is perfect. As a corollary, we get injectivity statements for (additive) higher Chow groups as well as for motivic cohomology (with modulus) with $\mathbb{Z}/p$ coefficients when $k$ is algebraically closed.
