Abstract

We consider Shimura varieties associated to a unitary group of signature $(n - 2, 2)$ . We give regular $p$ -adic integral models for these varieties over odd primes $p$ which ramify in the imaginary quadratic field with level subgroup at $p$ given by the stabilizer of a selfdual lattice in the hermitian space. Our construction is given by an explicit resolution of a corresponding local model.

夯素上一些单元式志村变的半可变模型

我们考虑的是与签名为 (n- 2,2) 的单元群相关联的志村变项。我们给出了这些奇数素数 p 上的正规 p-adic 积分模型，这些模型在虚二次域中发生斜伸，其 p 处的水平子群由赫米提空间中自偶晶格的稳定子给出。我们的构造由相应局部模型的明确解析给出。

期刊介绍： ANT’s inclusive definition of algebra and number theory allows it to print research covering a wide range of subtopics, including algebraic and arithmetic geometry. ANT publishes high-quality articles of interest to a broad readership, at a level surpassing all but the top four or five mathematics journals. It exists in both print and electronic forms. The policies of ANT are set by the editorial board — a group of working mathematicians — rather than by a profit-oriented company, so they will remain friendly to mathematicians'' interests. In particular, they will promote broad dissemination, easy electronic access, and permissive use of content to the greatest extent compatible with survival of the journal. All electronic content becomes free and open access 5 years after publication.
