关于 SC-互反层张量积的一点注记

代数几何 2019-11-15 v3

摘要

我们用几何型 KK-群给出了带转移的 SC-互反预层张量积的描述,并研究了 Ga\mathbb{G}_aGa\mathbb{G}_a 张量积的结构。我们将该描述应用于刻画曲线乘积的带模 0-圈 Chow 群。我们还证明了 Ga\mathbb{G}_aGm\mathbb{G}_m 的张量积同构于 Kähler 微分形式层 Ω1\Omega^1,作为特征零上的互反层。

备注

The notion of tensor product in the category of SC-reciprocity sheaves was not correct. We don't know whether this category has a symmetric monoidal structure. But the results in this paper survive in much more suitable way. See arXiv:1911.05291
