一句话:为完备 Heyting 与 co-Heyting 代数给出新的序理论刻画,并揭示其与 Nash 均衡的意外联系。
论文针对完备且同时具有 Heyting 与 co-Heyting 结构的代数 C,提出一种新的序理论刻画。该刻画不依赖传统代数公理表述,而是基于 C 的子完备子格上的 Veinott 序关系。Veinott 序关系在 Topkis 定理中起关键作用,而 Topkis 定理被用于分析超模博弈中 Nash 均衡的序理论结构。由此,作者在完备 Heyting 与 co-Heyting 代数的刻画与 Nash 均衡研究之间建立了一个意想不到的联系。摘要未报告实验评估,结果以数学定理和序理论推导的形式呈现,属于理论研究。
We give a new order-theoretic characterization of a complete Heyting and co-Heyting algebra $C$. This result provides an unexpected relationship with the field of Nash equilibria, being based on the so-called Veinott ordering relation on subcomplete sublattices of $C$, which is crucially used in Topkis' theorem for studying the order-theoretic stucture of Nash equilibria of supermodular games.Comment: To appear in Logical Methods in Computer Science
