阿贝尔范畴的形变理论

Deformation theory of abelian categories

Wenty T. Lowen, Michel Van den Bergh

摘要:

本文发展了阿贝尔范畴的基本无穷小形变理论。这个理论产生了一个自然的推广著名的变形代数论开发的Gerstenhaber。作为变形理论的一部分,我们定义了阿贝尔范畴的平坦性概念。我们发现,各种基本属性下保持平坦的变形,我们构造几个变形问题之间的等价。

英文摘要:

In this paper we develop the basic infinitesimal deformation theory of abelian categories. This theory yields a natural generalization of the well-known deformation theory of algebras developed by Gerstenhaber. As part of our deformation theory we define a notion of flatness for abelian categories. We show that various basic properties are preserved under flat deformations and we construct several equivalences between deformation problems.
