代数曲面上Parshin互反律的范畴证明
A categorical proof of the Parshin reciprocity laws on algebraic surfaces
摘要:
本文定义并研究了Picard广群上的2-范畴的扭体、群的中心扩张以及中心扩张中的换位子映射。利用它在二维局部域和二维椭圆理论的背景下,我们得到了二维驯服符号和一个新的证明Parshin倒易律的代数曲面。
英文摘要:
We define and study the 2-category of torsors over a Picard groupoid, a central extension of a group by a Picard groupoid, and commutator maps in this central extension. Using it in the context of two-dimensional local fields and two-dimensional adelic theory we obtain the two-dimensional tame symbol and a new proof of Parshin reciprocity laws on an algebraic surface.
