摘要

本文给出了有限维向量空间中独立随机向量之和的反集中边界。特别是，我们渐近地建立了利德和拉德克里夫的猜想（SIAM J Discrete Math 7:90-101, 1994）和琼斯的问题（SIAM J Appl Math 34:1-6, 1978）。这项工作的亮点是 Chudnovsky 等人 (Ann Math 164:51-229, 2006) 在反集中背景下对强完美图定理的应用。

Anticoncentration of Random Vectors via the Strong Perfect Graph Theorem

In this paper we give anticoncentration bounds for sums of independent random vectors in finite-dimensional vector spaces. In particular, we asymptotically establish a conjecture of Leader and Radcliffe (SIAM J Discrete Math 7:90–101, 1994) and a question of Jones (SIAM J Appl Math 34:1–6, 1978). The highlight of this work is an application of the strong perfect graph theorem by Chudnovsky et al. (Ann Math 164:51–229, 2006) in the context of anticoncentration.
