Abstract

Let kk be a field of positive characteristic pp, and XX be a separated of finite type kk-scheme of dimension dd. 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 kk is perfect. As a corollary, we get injectivity statements for (additive) higher Chow groups as well as for motivic cohomology (with modulus) with Z/p\mathbb{Z}/p coefficients when kk is algebraically closed.
