摘要翻译:
给出了一个noetherian局部区域$R$和它的分数域在$R$上的非负的值$\nu$,我们得到了与位于$\nu$的值群$\gamma$中某些部分的值相对应的$R$不同值理想的数目增长的一些非常一般的界。我们证明了这个增长条件对noetherian$R$的半群$\nu(R\setminus\{0})$施加了比前文引用第一作者的{C2}更强的限制。给定一个有序嵌入的$\gamma\子集({\mathbf R}^h)_{\hbox{\rm lex}}$,其中$h$是$\nu$的秩,我们还研究了$\gamma$中自然出现的部分在${\mathbf R}^h$中的形状。我们给出的例子表明,这种形状可以是非常野生的,它不依赖于嵌入,并表明它是半群$\nu(R\setminus\{0})$复杂性的一个很好的指示符。

英文摘要:
Given a noetherian local domain $R$ and a valuation $\nu$ of its field of fractions which is non negative on $R$, we derive some very general bounds on the growth of the number of distinct valuation ideals of $R$ corresponding to values lying in certain parts of the value group $\Gamma$ of $\nu$. We show that this growth condition imposes restrictions on the semigroups $\nu(R\setminus \{0\})$ for noetherian $R$ which are stronger that those resulting from the previous paper \cite{C2} of the first author. Given an ordered embedding $\Gamma\subset ({\mathbf R}^h)_{\hbox{\rm lex}}$, where $h$ is the rank of $\nu$, we also study the shape in ${\mathbf R}^h$ of the parts of $\Gamma$ which appear naturally in this study. We give examples which show that this shape can be quite wild in a way which does not depend on the embedding and suggest that it is a good indicator of the complexity of the semigroup $\nu(R\setminus \{0\})$.
