论文摘要
相对论的一般理论可以等效地在平坦的时空上，与非呈现非中性非属性标量$ q $的无扭转仿射连接相关联。在本文中，我们介绍了这一点的扩展，即$ f（q）$重力理论，并在各向异性bianchi-i模型的背景下探索宇宙的早期演变。通过其几何修饰，在当前环境中的$ f（q）$理论在解释较晚的膨胀方面非常成功。在这里，我们注意到，它适合普朗克（Planck）合作集团对通货膨胀参数的最新发布的限制，但没有出色的进步，但在辐射时代占据主导的时代中未能产生可行的减速扩张。
General theory of relativity can be equivalently formulated on a flat space-time associating a torsion-free affine connection of non-vanishing non-metricity scalar $Q$. In this paper, we present an extension of this, viz., the $f(Q)$ theory of gravity, and explore the early evolution of the universe in the background of anisotropic Bianchi-I model. The $f(Q)$ theory in the current setting through its geometric modification is quite successful in explaining the late time accelerated expansion. Here we note that it accommodates latest released constraints on the inflationary parameters by Planck's collaboration group with excellent precession, but fails to produce a viable decelerated expansion in the radiation dominated era.
