Newton polygons for $L$ -functions of generalized Kloosterman sums

Chunlin Wang, Liping Yang

In this paper, we study the Newton polygons for the $L$ -functions of $n$ -variable generalized Kloosterman sums. Generally, the Newton polygon has a topological lower bound, called…

$L$ -functions for families of generalized Kloosterman sums and $p$ -adic differential equations

Chunlin Wang, Liping Yang

In this paper, we focus on a family of generalized Kloosterman sums over the torus. With a few changes to Haessig and Sperber's construction, we derive some relative $p$ -adic cohom…
