Let X $X$ X be a compact complex space in Fujiki's Class C $\mathcal {C}$ C. We show that the group Aut ( X ) $\operatorname{Aut}(X)$ Aut(X) of all biholomorphic automorphisms of X $X$ X has the Jordan property: there is a (Jordan) constant J = J ( X ) $J = J(X)$ J=J(X) such that any finite subgroup G Aut ( X ) $G\leqslant \operatorname{Aut}(X)$ has an abelian subgroup H G $H\leqslant G$ with the index [ G : H ] J $[G:H]\leqslant J$ . This extends, with a quite different method, the result of Prokhorov and Shramov for Moishezon threefolds.

Fujiki 类 C$\mathcal {C}$ 紧空间自同构群的 Jordan 属性

X $X$ X在藤木的课堂上成为一个紧凑的复杂空间 C $\数学{C}$ C. 我们表明该组 自动 ( X ) $\运营商名称{Aut}(X)$ 自动( X)的所有双全纯自同构 X $X$ X有 Jordan 属性:有一个 (Jordan) 常数 Ĵ = Ĵ ( X ) $J = J(X)$ Ĵ= J( X)使得任何有限子群 G 自动 ( X ) $G\leqslant \operatorname{Aut}(X)$ 有一个阿贝尔子群 H G $H\leqslant G$ 与索引 [ G H ] Ĵ $[G:H]\leqslant J$ . 这以一种完全不同的方法扩展了 Prokhorov 和 Shramov 对 Moishezon 的结果三倍。
