摘要翻译:
本文定义了有限子集$D\子集\ma{N}^r$的$P$-密度,并证明了它给出了特征为$P$的有限域上指数和的$P$-adic值的一个很好的下界。我们还给出了一个应用:当$r=1$时,$p$-密度是Artin-Schreier曲线族的一般牛顿多边形的第一斜率,它与指数在$d$中的多项式有关。

英文摘要:
In this paper we define the $p$-density of a finite subset $D\subset\ma{N}^r$, and show that it gives a good lower bound for the $p$-adic valuation of exponential sums over finite fields of characteristic $p$. We also give an application: when $r=1$, the $p$-density is the first slope of the generic Newton polygon of the family of Artin-Schreier curves associated to polynomials with their exponents in $D$.
