Abstract

Let \(X\) be a compact complex space in Fujiki’s class \(\mathcal{C}\). In this paper, we show that \(X\) admits a compact Kähler model \({\tilde X}\), that is, there exists a projective bimeromorphic map \(\sigma\colon\tilde{X}\to X\) from a compact Kähler manifold \(\tilde{X}\) such that the automorphism group \(\operatorname{Aut}(X)\) lifts holomorphically and uniquely to a subgroup of \(\operatorname{Aut}({\tilde X})\). As a consequence, we also give a few applications to the Jordan property, the finiteness of torsion groups, and arbitrary large finite abelian subgroups for compact complex spaces in Fujiki’s class \({\mathcal C}\).

论某些紧凑复数空间的等变凯勒模型的存在性
Abstract Let \(X\) be a compact complex space in Fujiki's class \(\mathcal{C}\).在本文中,我们证明了 \(X\) 承认一个紧凑的 Kähler 模型 \({\tilde X}\),也就是说、存在一个从紧凑凯勒流形(\tilde{X}\)到 X 的投影双目映射(\sigma\colon\tilde{X}\to X),使得自变群(\(\operatorname{Aut}(X)\) lifts holomorphically and uniquely to a subgroup of \(\operatorname{Aut}({\tilde X})\)。因此,我们还给出了一些关于乔丹性质、扭转群的有限性以及藤木类 \({\mathcal C}\) 中紧凑复空间的任意大有限无边子群的应用。
