论文摘要

在这项工作中,我们探讨了重力多项式仿射模型的三维公式,该模型是通过从基本磁场集中排除度量标准来放松等价原理来扩展一般相对性的模型。特别是,为了洞悉引力模型中扭转和非赞成度的作用,我们考虑了均匀和各向同性宇宙学模型,为此,它们的溶液被分类为\ emph {决策树}。我们还展示了其中一些明确的解决方案,这些解决方案允许定义(替代/紧急)从连接得出的指标。

In this work, we explore a three-dimensional formulation of the polynomial affine model of gravity, which is a model that extends general relativity by relaxing the equivalence principle through the exclusion of the metric from the set of fundamental fields. In particular, in an attempt to gain insight of the role of the torsion and nonmetricity in the gravitational models, we consider homogeneous and isotropic cosmological models, for which their solutions are classified in a \emph{decisions tree}. We also show a few of these explicit solutions that allow the definition of (alternative/emergent) metrics derived from the connection.
