从具有路径无关选择函数的多对一匹配市场到一对一匹配市场的分解

A decomposition from a many-to-one matching market with path-independent choice functions to a one-to-one matching market

Pablo Neme, Jorge Oviedo

AI总结:

本文利用 Aizerman-Malishevski 分解将路径无关选择函数下的多对一匹配市场转化为关联一对一市场,提出新稳定性概念并建立稳定匹配同构,还改编延迟接受算法并证明乡村医院定理。

摘要:

对于企业被赋予路径无关选择函数的多对一市场,我们基于 Aizerman-Malishevski 分解定义了一个关联的一对一市场。鉴于一对一市场通常的稳定性概念并不很适合这一关联的一对一市场,我们引入了一种新的稳定性概念。该概念使我们能够在多对一市场的稳定匹配集合,与关联的一对一市场中满足这一新稳定性准则的匹配集合之间建立同构。此外,我们提出了对著名的延迟接受算法的一种改编,用于计算在关联的一对一市场中满足这一新稳定性概念的匹配。最后,作为我们同构的副产品,我们证明了所谓“乡村医院定理”的一个改编版本。

英文摘要:

For a many-to-one market where firms are endowed with path-independent choice functions, based on the Aizerman-Malishevski decomposition, we define an associated one-to-one market. Given that the usual notion of stability for a one-to-one market does not fit well for this associated one-to-one market, we introduce a new notion of stability. This notion allows us to establish an isomorphism between the set of stable matchings in the many-to-one market and the matchings in an associated one-to-one market that meet this new stability criterion. Furthermore, we present an adaptation of the well-known deferred acceptance algorithm to compute a matching that satisfies this new notion of stability for the associated one-to-one market. Finally, as a byproduct of our isomorphism, we prove an adapted version of the so-called Rural Hospital Theorem.
