与Drinfeld模相关的精细Selmer群的岩泽理论

摘要

qq为素数幂,F=Fq(T)F=\mathbb{F}_q(T)Fq\mathbb{F}_q(含qq个元素的域)上的有理函数域。设ϕ\phiFF上的Drinfeld模,p\mathfrak{p}A:=Fq[T]A:=\mathbb{F}_q[T]的非零素理想。在FF的常数Zp\mathbb{Z}_p-扩张上,我们引入与ϕ\phip\mathfrak{p}-准素挠相关的精细Selmer群。我们证明其为ApA_{\mathfrak{p}}上的余有限生成模。这证明了此情形下岩泽μ=0\mu=0猜想的类比,并为本文所引入对象的进一步研究提供了背景。
