论文摘要
在本文中，我们在抽象经济中介绍了$δ$ - 概念的概念，所有选择集都是一般拓扑空间。我们通过放松$ ss $ -Convexity至$δ$ -Convexity，对抽象经济体中经典的Yannelis-Prabhakar平衡存在进行了新的概括。
In this paper, we introduce the concept of $Δ$-convexity in an abstract economy with all choice sets being general topological spaces. We give a new generalization of the classical Yannelis-Prabhakar equilibrium existence theorem in abstract economies by relaxing $SS$-convexity to $Δ$-convexity.
