An equivalent conjecture to Feige's Conjecture

Probability 2025-09-17 v2 Combinatorics

Abstract

Let X1, ..., Xn be arbitrary non-negative independent random variables with respective expected values μi\mu_{i} at most one. We sketch but do not prove an equivalent conjecture to Feige's Conjecture P(i=1nXi<μ+1)exp(1)\mathbb{P} \left( \sum_{i=1}^{n} X_{i} < \mu + 1 \right) \geq \exp \left(-1 \right), where μ\mu is the expected value of the sum of the random variables. We show by a simple example how this inequality finds use in mathematical finance.

4 pages. In v1 I claimed a proof of Feige's Conjecture. The proof, however, was flawed
