In this paper we show that Cartan geometries can be studied via transitive Lie groupoids endowed with a special kind of vector-valued multiplicative 1-forms. This viewpoint leads us to a more general notion, that of Cartan bundle, which encompasses both Cartan geometries and G-structures.

Cartan几何和乘法形式

在本文中，我们表明，可以通过赋予特殊矢量值乘积1形式的传递李群群研究Cartan几何。这种观点使我们想到了更通用的概念，即Cartan束，它既包含Cartan几何形状又包含G结构。
