论文摘要
我们为受Brans-Dicke Gravity启发的不同$ g $ newtonian的理论提出了一种拉格朗日公式。与其在文献中以前所做的那样，在我们的提议中，$ g $的运行自然来自理论的内部动力结构，而不是对引力耦合施加{\ it Ad hoc}的依赖性。我们探讨了所得的重力场的特征，用于静态和球体对称的质量分布以及宇宙学框架中的特征。
We propose a Lagrangian formulation for a varying $G$ Newtonian-like theory inspired by the Brans-Dicke gravity. Rather than imposing an {\it ad hoc} dependence for the gravitational coupling, as previously done in the literature, in our proposal the running of $G$ emerges naturally from the internal dynamical structure of the theory. We explore the features of the resulting gravitational field for static and spherically symmetric mass distributions as well as within the cosmological framework.
