摘要:

本文研究随机$p$-进矩阵余核的联合分布。设$p$为素数,$P_1(t), \cdots, P_l(t) \in \mathbb{Z}_p[t]$为首一多项式,它们模$p$后在$\mathbb{F}_p[t]$中的约化是互异且不可约的。我们确定了当$n \rightarrow \infty$时,$\mathbb{Z}_p$上服从Haar测度的随机$n \times n$矩阵$A$对应的余核$\text{cok}(P_1(A)), \cdots, \text{cok}(P_l(A))$的联合分布极限。通过应用随机矩阵模型的线性化方法,我们还提出了一个推广该结果的猜想。最后,我们给出了一个充分条件,使得当$n \rightarrow \infty$时,余核$\text{cok}(A)$与$\text{cok}(A+B_n)$相互独立,其中对每个$n$,$B_n$是$\mathbb{Z}_p$上的固定$n \times n$矩阵,$A$是$\mathbb{Z}_p$上的随机$n \times n$矩阵。

英文摘要:

In this paper, we study the joint distribution of the cokernels of random $p$-adic matrices. Let $p$ be a prime and $P_1(t), \cdots, P_l(t) \in \mathbb{Z}_p[t]$ be monic polynomials whose reductions modulo $p$ in $\mathbb{F}_p[t]$ are distinct and irreducible. We determine the limit of the joint distribution of the cokernels $\text{cok} (P_1(A)), \cdots, \text{cok}(P_l(A))$ for a random $n \times n$ matrix $A$ over $\mathbb{Z}_p$ with respect to Haar measure as $n \rightarrow \infty$. By applying the linearization of a random matrix model, we also provide a conjecture which generalizes this result. Finally, we provide a sufficient condition that the cokernels $\text{cok}(A)$ and $\text{cok}(A+B_n)$ become independent as $n \rightarrow \infty$, where $B_n$ is a fixed $n \times n$ matrix over $\mathbb{Z}_p$ for each $n$ and $A$ is a random $n \times n$ matrix over $\mathbb{Z}_p$.
