论文摘要
本文扩展了两个最新提案，分别是\ cite {susskind：2021dfc} \ cite {susskind：2021esx}和\ cite {shaghoulian：2021cef}，用于概括ryu-takayanagi和ryu-takayanagi和hubeny-takaniy-takayani-takayanagianagianagianagianagi sitter sitter sitter sitter sitter。建议（称为单层和双层提案）相似。两者都将广告的边界替换为静态斑点的边界 - 换句话说。在说明每个规则后，我们将其应用于许多案件，并表明它们以其他理由产生预期的结果。 单层和双层建议通常会产生相同的结果，但在某种情况下，他们不同意。为了确切地决定它们，我们需要更多地了解全息系统热力学极限的性质。
This paper expands on two recent proposals, \cite{Susskind:2021dfc}\cite{Susskind:2021esx} and \cite{Shaghoulian:2021cef}, for generalizing the Ryu-Takayanagi and Hubeny-Rangamani-Takayanagi formulas to de Sitter space. The proposals (called the monolayer and bilayer proposals) are similar; both replace the boundary of AdS by the boundaries of static-patches--in other words event horizons. After stating the rules for each, we apply them to a number of cases and show that they yield results expected on other grounds. The monolayer and bilayer proposals often give the same results, but in one particular situation they disagree. To definitively decide between them we need to understand more about the nature of the thermodynamic limit of holographic systems.
