Abstract. A remarkable conjecture of Feige [SIAM J. Comput., 35 (2006), pp. 964–984] asserts that for any collection of [math] independent nonnegative random variables [math], each with expectation at most 1, [math], where [math]. In this paper, we investigate this conjecture for the class of discrete log-concave probability distributions, and we prove a strengthened version. More specifically, we show that the conjectured bound [math] holds when [math]’s are independent discrete log-concave with arbitrary expectation.

关于离散对数凹分布的 Feige 猜想

SIAM 离散数学杂志,第 38 卷,第 1 期,第 93-102 页,2024 年 3 月。
摘要。Feige 的一个引人注目的猜想 [SIAM J. Comput., 35 (2006), pp. 964–984] 断言,对于任何 [数学] 独立非负随机变量 [数学] 的集合,每个变量的期望值最多为 1,[数学] ,其中[数学]。在本文中,我们研究了离散对数凹概率分布类的猜想,并证明了一个增强版本。更具体地说,我们证明当 [math] 是具有任意期望的独立离散对数凹时,猜想的界限 [math] 成立。
