论文摘要
非局部重力（NLG）是基于与培养基的非局部电动力学的一定类比对爱因斯坦重力理论的经典非局部概括。历史依赖性通过涉及因果内核的构型关系进入NLG，该关系最终应通过观察数据确定。本文的目的是重新重新进行非局部重力，以便本构之间的非局部方面直接连接可测量的数量，如介质的非局部电动力学。结果的构成关系与Puetzfeld，Obukhov和Hehl [25]的最新建议相吻合。通过NLG的新构型关系，可以证明Sitter Spacetime不是NLG的解决方案。
Nonlocal gravity (NLG) is a classical nonlocal generalization of Einstein's theory of gravitation based on a certain analogy with the nonlocal electrodynamics of media. The history dependence enters NLG through a constitutive relation involving a causal kernel that should ultimately be determined via observational data. The purpose of this paper is to reformulate nonlocal gravity such that the nonlocal aspect of the constitutive relation directly connects measurable quantities as in the nonlocal electrodynamics of media. The resulting constitutive relation turns out to coincide with the recent suggestion of Puetzfeld, Obukhov, and Hehl [25]. With the new constitutive relation of NLG, it is possible to show that de Sitter spacetime is not a solution of NLG.
