具有大$\mathcal L$ -不变量的$2$ -维半稳定表示的约化
Reductions of $2$-dimensional semi-stable representations with large $\mathcal L$-invariant
摘要:
我们确定减少2维,不可约,半稳定,和非结晶表示的$\mathrm{Gal}(\overline{\mathbb Q}_p/\mathbb Q_p)$与霍奇-泰特权重$0 < k-1$和$\mathcal L$不变的$p$ -进规范是足够大的,取决于$k$。我们的主要结果提供了第一个系统的例子减少$k \geq p$。
英文摘要:
We determine reductions of 2-dimensional, irreducible, semi-stable, and non-crystalline representations of $\mathrm{Gal}(\overline{\mathbb Q}_p/\mathbb Q_p)$ with Hodge--Tate weights $0 < k-1$ and with $\mathcal L$-invariant whose $p$-adic norm is sufficiently large, depending on $k$. Our main result provides the first systematic examples of the reductions for $k \geq p$.
