关于$(S,\{2\})$ -精化类数的增长性

On the growth of the $(S,\{2\})$-refined class number

Eugenio Finat

摘要:

我们给出了一个新的证明,证明了$h_{n,2}^{-}$的$p$ -进赋值的增长(相对于$n$)是线性的,其中$h_{n,2}^{-}$表示分圆域$\mathbb{Q}(μ_{p^{n+1}})$的$(S,\{2\})$ -精化类数的负部分,如Hu和Kim在[J. of Number Theory 158(2016),73-89]中定义的。作为我们证明的结果,我们得到了$h_{n,2}^{-}$的$p$ -adic赋值和$h_{n}^{-}$的$p$ -adic赋值之间的显式关系,$h_{n}^{-}$是分圆域$\mathbb{Q}(μ_{p^{n+1}})$的类数$h_n$的减部分.

英文摘要:

We give a new proof of the fact that the growth (with respect to $n$) of the $p$-adic valuation of $h_{n,2}^{-}$ is linear, where $h_{n,2}^{-}$ denotes the minus part of the $(S,\{2\})$-refined class number of the cyclotomic field $\mathbb{Q}(μ_{p^{n+1}})$, as defined by Hu and Kim in [J. of Number Theory 158 (2016), 73-89]. As a consequence of our proof, we obtain an explicit relation between the $p$-adic valuation of $h_{n,2}^{-}$ and the $p$-adic valuation of $h_{n}^{-}$, the minus part of the class number $h_n$ of the cyclotomic field $\mathbb{Q}(μ_{p^{n+1}})$.
