序列的块划分

Block Partitions of Sequences

Imre Bárány, Victor S. Grinberg

摘要:

给定序列A=(a1,...,an),A的块B是集合B={ai,.,aj},其中i<=j或空集。块B的大小b是其元素的总和。当0<=ai<=1且k为正整数时,A可划分为k个块B1,.,Bk与|比-BJ|对于每个i,j <=1,我们在许多方向上推广了这个结果。

英文摘要:

Given a sequence A=(a1,...,an) of real numbers, a block B of the A is either a set B={ai,...,aj} where i<=j or the empty set. The size b of a block B is the sum of its elements. We show that when 0<=ai<=1 and k is a positive integer, there is a partition of A into k blocks B1,...,Bk with |bi-bj|<=1 for every i, j. We extend this result in many directions.
