论文摘要
多项式仿射重力是重力的替代模型，其基本场是仿射连接，并且在完整的差异性群体下是不变的。在3+1个尺寸中，场方程概括了爱因斯坦 - 希尔伯特（Hilbert）的耦合常数是无尺寸的，但该动作的术语数量有限，尽管该动作并不涉及（基本的）度量，但某些度量张量的场可能\ emph emph emph {Emph {emerge}。只要宇宙学安萨兹（Ansatz），将讨论各种宇宙学模型的特性。
The polynomial affine gravity is an alternative model of gravity whose fundamental field is the affine connection, and it is invariant under the complete group of diffeomorphisms. In 3+1 dimensions the field equations generalise those of Einstein--Hilbert, the coupling constants are dimensionless, the action has a finite numbers of term, and although the action does not involve a (fundamental) metric, some metric tensor fields might \emph{emerge} from the connection. Provided a cosmological ansatz, the properties of diverse cosmological models are discussed.
