Abstract

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×nn\times n matrices with entries valued in the domain. Previously, Wood found that when the entries of a random n×nn\times n integral matrix are not too concentrated modulo a prime, the asymptotic distribution (as nn\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.
