$U(3)$算术流形的上同调格

Lattices in the cohomology of $U(3)$ arithmetic manifolds

Daniel Le

摘要:

根据泰勒-怀尔斯方法所需的假设,我们证明了形式的$U(3)$,这是紧凑的无穷大的格子结构上凹代数向量或主列类型所给出的$λ$ -同型部分的完全上同调是一个局部不变的伽罗瓦表示附加到$λ$时,这伽罗瓦表示是剩余不可约的局部地方划分$p$。作为一个关键的输入,我们建立相应的模$p$多重性一的结果。本文的主要创新点是将积分Hecke理论与Taylor-Wiles方法相结合。

英文摘要:

Under hypotheses required for the Taylor-Wiles method, we prove for forms of $U(3)$ which are compact at infinity that the lattice structure on upper alcove algebraic vectors or on principal series types given by the $λ$-isotypic part of completed cohomology is a local invariant of the Galois representation attached to $λ$ when this Galois representation is residually irreducible locally at places dividing $p$. As a crucial input, we establish corresponding mod $p$ multiplicity one results. Our main innovation is the combination of integral Hecke theory and the Taylor--Wiles method.
