Hrushovski's suggestion, given in [3], to capture the structure of the 1-analysable covers of a theory T using simplicial groupoids definable in T is realized here. The ideas of Haykazyan and Moosa, found in [“Functoriality and uniformity in Hrushovski's groupoid-cover correspondence,” Annals of Pure and Applied Logic, 2018] are used, and extended, to define an equivalence of categories. Finally, a couple of examples are studied with these new tools.

使用简单群像扩展Hrushovski的群像-封面对应关系

赫鲁斯托夫斯基的建议（在[3]中给出）使用可在T中定义的简单类群来捕获理论T的1个可分析封面的结构。Haykazyan和Moosa的思想在[Hrushovski的groupoid-cover对应关系中的功能性和统一性，《纯粹与应用逻辑学年鉴》，2018年]中被使用和扩展，以定义类别的等价性。最后，使用这些新工具研究了几个示例。
