Abstract

Abstract The real sequence (xn) is maldistributed if for any non-empty interval I, the set {n ∈𝕅 : xn ∈I} has upper asymptotic density 1. The main result of this note is that the set of all maldistributed real sequences is a residual set in the set of all real sequences (i.e., the maldistribution is a typical property in the sense of Baire categories). We also generalize this result.

非分布序列集的拓扑性质
如果对于任意非空区间I,集{n∈𝕅:xn∈I}具有上渐近密度1,则实序列(xn)是非分布的。这篇笔记的主要结论是,所有非分布实序列的集合是所有实序列集合中的残集(即,非分布是贝尔范畴意义上的一个典型性质)。我们也推广了这个结果。
