Abstract

We study the moduli of anti-invariant Higgs bundles as introduced by Zelaci. Using recent existence results of Alper, Halpern-Leistner and Heinloth we establish the existence of a separated good moduli space for semistable anti-invariant Higgs bundles. Along the way this produces a non-GIT proof of the existence of a separated good moduli space for semistable Higgs bundles. We also prove the properness of the Hitchin system in this setting.

反不变希格斯束的模量
我们研究了泽拉西(Zelaci)提出的反不变希格斯束的模空间。利用阿尔珀(Alper)、哈尔彭-莱斯特纳(Halpern-Leistner)和海因洛特(Heinloth)的最新存在性结果,我们证明了半可变反不变希格斯束的分离良好模空间的存在性。同时,我们还证明了半可变希格斯束的分离良好模空间的适当性。我们还证明了希钦系统在这种情况下的适当性。
