论文摘要
这是关于在一个领域上派生的非均匀Koszul二元性的概述，主要基于作者的回忆录Arxiv：0905.2621。该论文旨在用作教学介绍，并摘要DG-代数与弯曲的DG-Coalgebras之间的协方差二元性，以及DG模块，CDG-Comodules和CDG-Contramodules之间的试验。一些个人回忆是历史讨论的一部分。
This is an overview on derived nonhomogeneous Koszul duality over a field, mostly based on the author's memoir arXiv:0905.2621. The paper is intended to serve as a pedagogical introduction and a summary of the covariant duality between DG-algebras and curved DG-coalgebras, as well as the triality between DG-modules, CDG-comodules, and CDG-contramodules. Some personal reminiscences are included as a part of historical discussion.
