标题： A polynomial affine model of gravity: after ten years

摘要： 引力的多项式仿射模型被提出作为度规引力和度规-仿射引力模型的替代方案。起初被认为是一种不可预测性的来源——作用量中存在许多项——后来证明是一个里程碑，因为它包含了所有可能的场组合，这些组合与微分同胚下的协变性相容。 在这里，我们回顾了该模型提出十年后对其分析所取得的进展，并概述了我们未来的研究方向。 显示英文摘要

摘要： The polynomial affine model of gravity was proposed as an alternative to metric and metric-affine gravitational models. What at the beginning was thought as a source of unpredictability, the presence of many terms in the action, turned out to be a milestone, since it contains all possible combinations of the fields compatible with the covariance under diffeomorphisms. Here, we present a review of the advances in the analysis of the model after ten years of its proposal, and sketch the guideline of our future perspectives.
