论文摘要
我们概括了建立公制的埃德丁顿（Eddington）启发的对应关系的算法（EIBI）重力与一般相对性（GR）与任何骨质物质部门之间的对应关系。在此过程中，提出了与任何公制的基于RICCI的重力（RBG）相关的度量兼容框架的抛光版本。特别关注从GR ConterPart生成RBG解决方案的问题，为EIBI案例提供了一般配方。这扩展了针对包括各向异性流体，标量场和电磁场的特定物质获得的先前结果。
We generalize the algorithm that establishes the correspondence between metric-affine Eddington-inspired Born-Infeld (EiBI) gravity and General Relativity (GR) to any bosonic matter sector. Along the way, a polished version of the proof of existence of a metric compatible frame associated to any metric-affine Ricci-Based Gravity (RBG) is presented. Particular attention is given to the problem of generating solutions of a RBG from the GR conterpart, providing a general recipe for the EiBI case. This extends previous results obtained for specific matter that included anisotropic fluids, scalar fields and electromagnetic fields.
