We show that the Suslin homology group with integral coefficients of a scheme $X$ separated of finite type over an algebraically closed field of characteristic 0 is a direct sum of a uniquely divisible group, finite copies of $\mathbb{Q}/\mathbb{Z}$, and a finitely generated group. We also study the possible type of homomorphisms between such groups induced by the morphisms of schemes.

关于特征零积分系数的 Suslin 同源性(附有 Bruno Kahn 的附录)

我们表明,在特征为 0 的代数闭域上具有有限类型的方案 $X$ 的积分系数的 Suslin 同调群是唯一可分群的直接和,$\mathbb{Q}/\mathbb 的有限副本{Z}$ 和有限生成群。我们还研究了由方案的态射引起的此类群之间可能的同态类型。
