AI总结:

该研究利用Wood的矩方法,针对元素取值于带有限商的可数戴德金整环的随机矩阵,提出并证明了一个可得到余核分布普适性结果的条件,拓展了此前整数矩阵场景下的相关结论。

摘要:

我们采用Wood的矩方法,研究元素取值于具有有限商的可数戴德金整环的随机n×n矩阵的余核所生成的有限模的分布。此前Wood发现,当随机n×n整数矩阵的元素模素数的分布不过于集中时,其余核的渐近分布(当n→∞时)与Cohen和Lenstra关于虚二次域类群分布的猜想相吻合。我们提出并证明了一个条件,该条件可针对元素取值于具有有限商的可数戴德金整环的随机矩阵,得到类似的普适性结果。

英文摘要:

We use the moment method of Wood to study the distribution of random finite modules over a countable Dedekind domain with finite quotients, generated by taking cokernels of random $n\times n$ matrices with entries valued in the domain. Previously, Wood found that when the entries of a random $n\times n$ integral matrix are not too concentrated modulo a prime, the asymptotic distribution (as $n\to\infty$) of the cokernel matches the Cohen and Lenstra conjecture on the distribution of class groups of imaginary quadratic fields. We develop and prove a condition that produces a similar universality result for random matrices with entries valued in a countable Dedekind domain with finite quotients.
