A sequence on the unit interval is said to have Poissonian pair correlation if for all reals , as . It is known that, if has Poissonian pair correlations, then the number of different gap lengths between neighboring elements of cannot be bounded along any index subsequence . First, we improve this by showing that, if has Poissonian pair correlations, then the maximum among the multiplicities of the neighboring gap lengths of is , as . Furthermore, we show that for every function with there exists a sequence with Poissonian pair correlations such that for all sufficiently large n. This answers negatively a question posed by G. Larcher.

关于具有泊松对相关性的序列间隙数
一个序列 在单位区间上被称为具有泊松对相关性,如果 对于所有实数 , 作为 . 据了解,如果 具有泊松对相关性,那么数 相邻元素之间的不同间隙长度 不能沿着任何索引子序列有界 . 首先,我们通过证明,如果 具有泊松对相关性,那么相邻间隙长度的多重性中的最大值 是 , 作为 . 此外,我们证明对于每个函数 和 存在一个序列 具有泊松对相关性,使得 对于所有足够大的n。这否定了 G. Larcher 提出的问题。
