如何用克矩阵切蛋糕

How to cut a cake with a gram matrix

Guillaume Chèze, Luca Amodei

摘要:

在这篇文章中,我们研究了公平分配问题。特别是,我们研究了一个概念,介绍了J. Barbanel,推广超级嫉妒自由公平分工。我们给出了一个新的证明。我们的方法允许我们给出这种公平划分的明确界限。此外,我们还对Barbanel在1996年提出的一个公开问题给出了理论上的回答。粗略地说,这个问题是:我们如何判断是否存在一个公平的划分满足一些不等式约束?此外,当所有的措施,给出了分段常数密度函数,然后我们展示了如何有效地构建这样一个公平的划分。

英文摘要:

In this article we study the problem of fair division. In particular we study a notion introduced by J. Barbanel that generalizes super envy-free fair division. We give a new proof of his result. Our approach allows us to give an explicit bound for this kind of fair division. Furthermore, we also give a theoretical answer to an open problem posed by Barbanel in 1996. Roughly speaking, this question is: how can we decide if there exists a fair division satisfying some inequalities constraints? Furthermore, when all the measures are given with piecewise constant density functions then we show how to construct effectively such a fair division.
