有限域上的T-adic指数和

T-adic exponential sums over finite fields

Chunlei Liu, Daqing Wan

摘要:

引入了与Laurent多项式$f$相关的$T$-进指数和.他们内插所有经典的$p^m$幂阶指数和相关的$f$。建立了$T$ -adic指数和的$L$ -函数的牛顿多边形的Hodge界.这个界限使我们能够确定,对于所有的$m$,牛顿多边形的$L$ -功能的$p^m$ -幂阶指数和相关的$f$是普通的$m=1$。进一步研究了$T$ -adic指数和的$L$ -函数的性质.在此过程中,新的开放问题的$T$ -进指数和本身进行了讨论。

英文摘要:

$T$-adic exponential sums associated to a Laurent polynomial $f$ are introduced. They interpolate all classical $p^m$-power order exponential sums associated to $f$. The Hodge bound for the Newton polygon of $L$-functions of $T$-adic exponential sums is established. This bound enables us to determine, for all $m$, the Newton polygons of $L$-functions of $p^m$-power order exponential sums associated to an $f$ which is ordinary for $m=1$. Deeper properties of $L$-functions of $T$-adic exponential sums are also studied. Along the way, new open problems about the $T$-adic exponential sum itself are discussed.
