给定理想类中的最小素理想

The least prime ideal in a given ideal class

Naser T. Sardari

摘要:

设$K$是一个数域,其判别式为$D_K$,类数为$h_{K}$,且在$\mathbb{Q}$上有界度.在GRH假设下,证明了$K$的每个理想类都包含一个范数小于$h_{K}^2\log(D_K)^{2}$的素理想,并且除了$o(h_K)$之外,都有一个范数小于$h_{K}\log(D_K)^{2+ε}$的素理想.对于虚二次域$K=\mathbb{Q}(\sqrt{D})$,通过假设猜想~ \ref{piarcor}(对相关猜想的一个弱版本),我们通过从我们的界中去除因子$\log(D)$来改进我们的界,并证明这些界是最优的.

英文摘要:

Let $K$ be a number field with the discriminant $D_K$ and the class number $h_{K}$, which has bounded degree over $\mathbb{Q}$. By assuming GRH, we prove that every ideal class of $K$ contains a prime ideal with norm less than $h_{K}^2\log(D_K)^{2}$ and also all but $o(h_K)$ of them have a prime ideal with norm less than $h_{K}\log(D_K)^{2+ε}$. For imaginary quadratic fields $K=\mathbb{Q}(\sqrt{D})$, by assuming Conjecture~\ref{piarcor} (a weak version of the pair correlation conjecure), we improve our bounds by removing a factor of $\log(D)$ from our bounds and show that these bounds are optimal.
