紧度量空间中的点分布,II

Point distributions in compact metric spaces, II

M. M. Skriganov

摘要:

我们考虑紧度量空间中的有限点子集(分布)。在一般可求长的度量空间中,给出了度量球中分布点间距离和的非平凡界以及分布的差异的非平凡界(定理1.1)。我们将Stolarsky的不变原理推广到距离不变空间(定理2.1)。对于任意度量空间,我们证明了一个概率不变原理(定理3.1)。此外,我们构造了一般可求长紧度量空间的等测度分拆为小平均直径的部分(定理4.1)。该版本的论文将发表在Mathematika上

英文摘要:

We consider finite point subsets (distributions) in compact metric spaces. In the case of general rectifiable metric spaces, non-trivial bounds for sums of distances between points of distributions and for discrepancies of distributions in metric balls are given (Theorem 1.1). We generalize Stolarsky's invariance principle to distance-invariant spaces (Theorem 2.1). For arbitrary metric spaces, we prove a probabilistic invariance principle (Theorem 3.1). Furthermore, we construct equal-measure partitions of general rectifiable compact metric spaces into parts of small average diameter (Theorem 4.1). This version of the paper will be published in Mathematika
