广义分歧表示的重数1

Multiplicity one for wildly ramified representations

Daniel Le

摘要:

设$F$是一个全实域,其中$p$是非分歧的.令$\overline{r}: G_F \rightarrow \mathrm{GL}_2(\overline{\mathbb{F}}_p)$是满足泰勒-怀尔斯假设的模伽罗瓦表示,并且在$p$之上的位置$v$处是通用的。设$\mathfrak{m}$为相应的Hecke本征系统。在$v$下满同余的Shimura曲线的模$p$上同调中的$\mathfrak{m}$ -挠率与Breuil和Paškirnas构造的$\mathrm{GL}_2(k_v)$ -表示$D_0(\overline{r}|_{G_{F_v}})$一致.特别地,它只依赖于局部表示$\overline{r}|_{G_{F_v}}$,并且它的Jordan-Hölder因子以重数1出现。这建立在和扩展的工作,作者与Morra和Schraen和独立的胡,王,证明了这些结果时,$\overline{r}|_{G_{F_v}}$被额外假定为tamely分歧。主要的新工具是利用多型tamely位势Barsotti-Tate变形环及其相交理论计算积分射影包络的Taylor-Wiles修补模的方法。

英文摘要:

Let $F$ be a totally real field in which $p$ is unramified. Let $\overline{r}: G_F \rightarrow \mathrm{GL}_2(\overline{\mathbb{F}}_p)$ be a modular Galois representation which satisfies the Taylor-Wiles hypotheses and is generic at a place $v$ above $p$. Let $\mathfrak{m}$ be the corresponding Hecke eigensystem. Then the $\mathfrak{m}$-torsion in the mod $p$ cohomology of Shimura curves with full congruence level at $v$ coincides with the $\mathrm{GL}_2(k_v)$-representation $D_0(\overline{r}|_{G_{F_v}})$ constructed by Breuil and Paškūnas. In particular, it depends only on the local representation $\overline{r}|_{G_{F_v}}$, and its Jordan-Hölder factors appear with multiplicity one. This builds on and extends work of the author with Morra and Schraen and independently of Hu-Wang, which proved these results when $\overline{r}|_{G_{F_v}}$ was additionally assumed to be tamely ramified. The main new tool is a method for computing Taylor-Wiles patched modules of integral projective envelopes using multitype tamely potentially Barsotti-Tate deformation rings and their intersection theory.
