摘要

Let K be a quadratic field, \(\mathcal {O}_K\) O K its ring of integers, and \(\mathfrak {a}\) a a square-free ideal of \(\mathcal {O}_K\) O K . In this paper, we investigate the distribution of ideals that divide \(\mathfrak {a}\) a using the Selberg–Delange method. We established that the Cesàro mean of distribution functions converges uniformly to the arcsine law in short intervals. This generalizes the result studied by Deshouillers–Dress–Tenenbaum and Cui–Wu.
