关于一般$p$ -adic域上的算术基本引理猜想

On the Arithmetic Fundamental Lemma conjecture over a general $p$-adic field

Andreas Mihatsch, Wei Zhang

摘要:

证明了具有奇剩余基数的一般$p$ -adic域上的算术基本引理猜想$q\geq \dim V$ .我们的策略类似于第二作者在证明$\mathbb{Q}_p$上的AFL(arXiv:1909.02697)时使用的策略,但只需要Shimura簇上除数生成序列的模块性(与其积分模型相反)。由此产生的灵活性的增加使我们能够在任意基域上工作。为了实现这一策略,我们还将Howard(arXiv:1303.0545)关于CM-圈交和Ehlen-Sankaran(arXiv:1607.06545)关于格林函数比较的结果从$\mathbb{Q}$推广到一般的全实基域.

英文摘要:

We prove the arithmetic fundamental lemma conjecture over a general $p$-adic field with odd residue cardinality $q\geq \dim V$. Our strategy is similar to the one used by the second author during his proof of the AFL over $\mathbb{Q}_p$ (arXiv:1909.02697), but only requires the modularity of divisor generating series on the Shimura variety (as opposed to its integral model). The resulting increase in flexibility allows us to work over an arbitrary base field. To carry out the strategy, we also generalize results of Howard (arXiv:1303.0545) on CM-cycle intersection and of Ehlen--Sankaran (arXiv:1607.06545) on Green function comparison from $\mathbb{Q}$ to general totally real base fields.
