四元数代数中积分结构的一些显式构造

Some explicit constructions of integral structures in quaternion algebras

Miriam Ciavarella, Lea Terracini

摘要:

设B是Q上的未定义四元数代数。在Hashimoto给出B中某些Eichler序的显式特征化之后,我们定义了这些序在矩阵的某些局部环中的显式嵌入,并描述了leven Nq的Eichler序在N层Eichler序中的两个自然包含.此外,我们提供了一个基础的链的Eichler秩序在B和证明结果的交集。

英文摘要:

Let B be an undefined quaternion algebra over Q. Following the explicit chacterization of some Eichler orders in B given by Hashimoto, we define explicit embeddings of these orders in some local rings of matrices; we describe the two natural inclusions of an Eichler order of leven Nq in an Eichler order of level N. Moreover we provide a basis for a chain of Eichler orders in B and prove results about their intersection.
