公共物品动态提供博弈的HK-δ-核心
The HK-δ-Core of the Dynamic Voluntary Provision of Public Goods

本文在一类$n$ -人公共物品动态提供博弈中，引入了HK-$\delta$ -核心解，证明当$n=2$ 时，HK-$\delta$ -核心与$\gamma$ -核心相等且非空；当$n\ge 3$ 时，HK-$\delta$ -核心作为$\gamma$ -核心的子集可能为空。
This paper presents the HK-$\delta$ -core in the dynamic voluntary provision of public goods. It shows that the HK-$\delta$ -core is equal to the$\gamma$ -core and non-empty in the 2-player case; it may be empty as the subset of the$\gamma$ -core in the multi-player case ($n\ge 3$ ).
