论文摘要
在这项研究中，我们考虑了麦克斯韦重力的宇宙学模型，该模型是通过测量半简单的庞贝省代数来构建的。受爱因斯坦 - 杨米尔斯理论的启发，我们用两个附加时间依赖的标量字段来描述麦克斯韦轨距场。在同质和各向同性的Friedmann-Lema- Robertson-Walker宇宙的背景下，我们将弗里德曼方程式得出以及新的贡献。此外，考虑到量表因子的指数演化，我们发现了其他标量场的精确表达式。此外，我们基于麦克斯韦代数研究了重力理论，并证明该模型导致了（反）de Sitter宇宙以及非加速宇宙模型。
In this study, we consider a cosmological model for the Maxwell gravity which is constructed by gauging the semi-simple extended Poincaré algebra. Inspired by the Einstein-Yang-Mills theory, we describe the Maxwell gauge field in terms of two additional time-dependent scalar fields. Within the context of a homogeneous and isotropic Friedmann-Lemaître-Robertson-Walker universe, we derive the Friedmann equations together with new contributions. Additionally, we find the exact expressions for the additional scalar fields, considering the exponential evolution of the scale factor. Moreover, we investigate the gauge theory of gravity based on the Maxwell algebra and demonstrate that this model leads to the (anti) de Sitter universe as well as a non-accelerated universe model.
