从$p$ Iwahori-Hecke模到$(φ,Γ)$ -模,II

From pro-$p$ Iwahori-Hecke modules to $(φ,Γ)$-modules, II

Elmar Grosse-Klönne

摘要:

设${\mathfrak o}$是${\mathbb Q}_p$的有限扩张域上的整数环,$k$是它的剩余域.设$G$是${\mathbb Q}_p$上的可裂约化群,${\mathcal H}(G,I_0)$是它的pro-$p$-Iwahori Hecke-代数${\mathfrak o}$.在\cite{dfun}中,我们介绍了如何从有限长的${\mathcal H}(G,I_0)$ -模到$(φ^r,Γ)$ -模,给某个附加选择的数据$(C^{(\bullet)},ϕ,τ)$赋予一个正合函子$M\mapsto{\bf D}(Θ_*{\mathcal V}_M)$的一般原理.在本文中,我们具体地计算了经典矩阵群的这种数据$(C^{(\bullet)},ϕ,τ)$。我们证明了相应的函子将(标准的)超奇异${\mathcal H}(G,I_0)\otimes_{\mathfrak o}k$ -模的集合与满足一定对称条件的$(φ^r,Γ)$ -模的集合等同起来。

英文摘要:

Let ${\mathfrak o}$ be the ring of integers in a finite extension field of ${\mathbb Q}_p$, let $k$ be its residue field. Let $G$ be a split reductive group over ${\mathbb Q}_p$, let ${\mathcal H}(G,I_0)$ be its pro-$p$-Iwahori Hecke ${\mathfrak o}$-algebra. In \cite{dfun} we introduced a general principle how to assign to a certain additionally chosen datum $(C^{(\bullet)},ϕ,τ)$ an exact functor $M\mapsto{\bf D}(Θ_*{\mathcal V}_M)$ from finite length ${\mathcal H}(G,I_0)$-modules to $(φ^r,Γ)$-modules. In the present paper we concretely work out such data $(C^{(\bullet)},ϕ,τ)$ for the classical matrix groups. We show that the corresponding functor identifies the set of (standard) supersingular ${\mathcal H}(G,I_0)\otimes_{\mathfrak o}k$-modules with the set of $(φ^r,Γ)$-modules satisfying a certain symmetry condition.
