摘要

K3（^{[m]}\）型极化超凯勒流形的周期形变给出了K3（^{[m]}\）型极化超凯勒流形模空间的每个连通分量嵌入其周期空间的情况，而周期空间是算术群的赫米对称域的商。继斯泰拉里和格里森科-胡莱克-桑卡兰的研究之后，我们研究了这些周期空间之间的覆盖映射的ramification，这些映射产生于一些等距群的作用。

Groups Acting on Moduli Spaces of Hyper-Kähler Manifolds

The period morphism of polarized hyper-Kähler manifolds of K3\(^{[m]}\)-type gives an embedding of each connected component of the moduli space of polarized hyper-Kähler manifolds of K3\(^{[m]}\)-type into their period space, which is the quotient of a Hermitian symmetric domain by an arithmetic group. Following work of Stellari and Gritsenko-Hulek-Sankaran, we study the ramification of covering maps between these period spaces that arise from the action of some groups of isometries.

期刊介绍： Milan Journal of Mathematics (MJM) publishes high quality articles from all areas of Mathematics and the Mathematical Sciences. The authors are invited to submit "articles with background", presenting a problem of current research with its history and its developments, the current state and possible future directions. The presentation should render the article of interest to a wider audience than just specialists. Many of the articles will be "invited contributions" from speakers in the "Seminario Matematico e Fisico di Milano". However, also other authors are welcome to submit articles which are in line with the "Aims and Scope" of the journal.
