The main goal of this paper is to characterize limit key polynomials for a valuation ν on . We consider the set of key polynomials for ν of degree α. We set p to be the exponent characteristic of ν. Our first main result (Theorem 1.1) is that if F is a limit key polynomial for , then the degree of F is for some . Moreover, in Theorem 1.2, we show that there exist and F a limit key polynomial for , such that the Q-expansion of F only has terms which are powers of p.

本文的主要目的是为极限ν刻画极限键多项式的特征。。我们考虑一套的关键多项式ν度的α。我们将p设为ν的指数特征。我们的第一个主要结果(定理1.1)是,如果F是,则F的度为 对于一些 。而且,在定理1.2中,我们证明存在和F为的极限键多项式,使得F的Q展开仅具有p的幂的项。
