随机对称p进矩阵等价类的分布

On the distribution of equivalence classes of random symmetric p-adic matrices

Valeriya Kovaleva

AI总结:

该研究针对奇素数$p$下服从$\u2124_p$上Haar测度的随机对称矩阵,推导其在多种等价关系下标准形的分布,并给出应用,为相关二次型非平凡零点概率的已有结果提供了新证明。

摘要:

我们考虑元素独立、服从$\u2124_p$上Haar测度的随机对称矩阵($p$为奇素数),推导其在若干等价关系下标准形的分布。我们给出了几个应用实例,包括为Bhargava、Cremona、Fisher、Jones和Keating关于$\u2124_p$上随机二次型具有非平凡零点的概率的结果提供另一种证明。

英文摘要:

We consider random symmetric matrices with independent entries distributed according to the Haar measure on $\mathbb{Z}_p$ for odd primes $p$ and derive the distribution of their canonical form with respect to several equivalence relations. We give a few examples of applications including an alternative proof for the result of Bhargava, Cremona, Fisher, Jones, and Keating on the probability that a random quadratic form over $\mathbb{Z}_p$ has a non-trivial zero.
