群胚无穷小理论的泛函方法

A Functorial Approach to the Infinitesimal Theory of Groupoids

Hirokazu Nishimura

摘要:

李代数胚作为群胚的无穷小对应体决不是自然的。在本文中,我们提出了一个函子结构称为西村代数胚的无限小对应群胚。西村代数胚,旨在微分几何,是相同的静脉作为Lawvere的函概念的代数理论和埃雷斯曼的函概念的理论称为草图。本文详细研究了完全不传递的Nishimura代数胚。最后,我们表明,西村代数胚自然产生李代数胚。

英文摘要:

Lie algebroids are by no means natural as an infinitesimal counterpart of groupoids. In this paper we propose a functorial construction called Nishimura algebroids for an infinitesimal counterpart of groupoids. Nishimura algebroids, intended for differential geometry, are of the same vein as Lawvere's functorial notion of algebraic theory and Ehresmann's functorial notion of theory called sketches. We study totally intransitive Nishimura algebroids in detail. Finally we show that Nishimura algebroids naturally give rise to Lie algebroids.
