论文摘要
本文的目的是在[5]中介绍的下降共同体（尖）集（尖头）方面对组的分类进行全面分类。我们表明，血统的共同体包括Serre的非亚洲群体共同体，作为一种特殊情况。这使我们能够进一步概括Serre的理论，以包括单体。
The aim of the paper is to give a full classification of factorizations of groups in terms of descent cohomology (pointed) sets introduced in [5]. We show that descent cohomology includes Serre's non-abelian group cohomology as a special case. This enables us to generalize Serre's theory further to include monoids.
