Arithmetic hypergeometric $D$ -modules and exponential sums on reductive groups

Lei Fu, Xuanyou Li, Chenhan Liu

For a finite family of representations of a reductive group, we define a Laurent polynomial on the group. The exponential sum associated this Laurent polynomial is called a hyperge…

$p$ -adic hypergeometric $D^{†} (\infty)$ -module and exponential sums on reductive groups

Xuanyou Li, Chenhan Liu

We study the $p$ -adic analogue of the $ℓ$ -adic hypergeometric sheaves for reductive groups, called the hypergeometric $D^{†} (\infty)$ -modules. They are overholon…
