模、定义域和Culler-Shalen范数

Modules, fields of definition, and the Culler-Shalen norm

Charles Katerba

摘要:

Culler-Shalen理论使用3-流形的SL(2,C)-特征簇的代数几何来构造流形中的本质曲面。有模结构与特征标簇的不可约分量的坐标环相关联,这些不可约分量与基本表面构造密切相关。当这些模块是非线性生成的,我们推导出一个公式,他们的排名,结合了不可约组件的领域的定义和Culler-Shalen规范。

英文摘要:

Culler-Shalen theory uses the algebraic geometry of the SL(2,C)-character variety of a 3-manifold to construct essential surfaces in the manifold. There are module structures associated to the coordinate rings of the irreducible components of character varieties that are intimately related to essential surface construction. When these modules are finitely generated, we derive a formula for their rank that incorporates the irreducible component's field of definition and the Culler-Shalen norm.
