分级和Koszul范畴

Graded and Koszul categories

Roberto Martinez-Villa, Øyvind Solberg

摘要:

Koszul代数出现在许多背景下;代数几何,组合数学,李代数,非交换几何和拓扑学。本文的目的和几个续集文件是表明,任何有限维代数总是有一个自然相关联的Koszul理论。为了得到这一点,Koszul代数,线性模和Koszul对偶的概念被扩展到添加剂(分次)领域。本文的主要重点是提供这些概括和必要的准备工作。

英文摘要:

Koszul algebras have arisen in many contexts; algebraic geometry, combinatorics, Lie algebras, non-commutative geometry and topology. The aim of this paper and several sequel papers is to show that for any finite dimensional algebra there is always a naturally associated Koszul theory. To obtain this, the notions of Koszul algebras, linear modules and Koszul duality are extended to additive (graded) categories over a field. The main focus of this paper is to provide these generalizations and the necessary preliminaries.
