本章包含2015年2月在巴塞罗那CRM上发表的关于霍尔代数的一系列讲座的扩展注释。霍尔代数理论的基本思想是,在一个精确范畴中的标志集合编码了一个结合乘法律。虽然斯坦尼茨和霍尔介绍了阿贝尔p-群的范畴,但很明显,原来的构造可以在更大的普遍性中应用,并允许许多有用的变化。这些笔记集中在更高的范畴方面的基础上的关系霍尔代数和瓦尔德豪森的S-建设。
This chapter contains extended notes for a series of lectures on Hall algebras given at the CRM Barcelona in February 2015. The basic idea of the theory of Hall algebras is that the collection of flags in an exact category encodes an associative multiplication law. While introduced by Steinitz and Hall for the category of abelian p-groups, it has since become clear that the original construction can be applied in much greater generality and admits numerous useful variations. These notes focus on higher categorical aspects based on the relation between Hall algebras and Waldhausen’s S-construction.
