一个通用变形环的计算

Computation of a universal deformation ring

Ariane Mezard

摘要:

本文计算了$(M/Q)$的一个具有上三角象的奇Galois二维表示的泛变形环,其中$M$是$F_{\infty}$在有限位置集S外未分歧的最大交换pro-$p$-扩张,$F_{\infty}$是由表示的核固定的域$K$的子扩张$F$的自由pro-$p$-扩张.我们建立了后一个通用变形环和通用变形环的Gal $(K_S/Q)$的表示,其中$K_S$是最大的亲$p$ -扩张的$K$以外的$S$未分歧。然后我们给出一些例子。这篇论文被接受发表在剑桥哲学学会数学学报(5月99日)。

英文摘要:

We compute the universal deformation ring of an odd Galois two dimensional representation of Gal$(M/Q)$ with an upper triangular image, where $M$ is the maximal abelian pro-$p$-extension of $F_{\infty}$ unramified outside a finite set of places S, $F_{\infty}$ being a free pro-$p$-extension of a subextension $F$ of the field $K$ fixed by the kernel of the representation. We establish a link between the latter universal deformation ring and the universal deformation ring of the representation of Gal$(K_S/Q)$, where $K_S$ is the maximal pro-$p$-extension of $K$ unramified outside $S$. We then give some examples. This paper was accepted for publication in the Mathematical Proceedings of the Cambridge philosophical society (May 99).
