p-adic随机代数是非分歧域的概率

The probability that a p-adic random étale algebra is an unramified field

Roy Shmueli

摘要:

研究了由独立同分布的随机多项式生成的随机代数。根据在$\mathbb{Z}_p$上归一化的Haar测度分布的系数。我们确定的概率,这个随机代数是一个unramified领域,明确。此外,我们证明了Bhargava,Cremona,Fisher和Gajović提出的猜想的一个私人案例。更准确地说,我们表明,这个概率是一个合理的$p$下,由$1/p$取代$p$不变的功能。

英文摘要:

We study the random étale algebra generated by a random polynomial with i.i.d. coefficients distributed according to Haar measure normalized on $\mathbb{Z}_p$. We determine the probability that this random algebra is an unramified field, explicitly. In addition, we prove a private case of a conjecture made by Bhargava, Cremona, Fisher, and Gajović. More precisely, we show that this probability is a rational function of $p$ that is invariant under replacing $p$ by $1/p$.
