研究了两类Abel范畴的recollement的构造.一种是从已知的两个Abel范畴的recollement构造一个Comma范畴的recollement;另一种是从一个已知的三角范畴的recollement构造函子范畴的子范畴A(S)的recollement.
Two kinds of recollements of abelian categories are constructed.One is the recollement of comma categories constructed from two known recollements of Abelian categories and the other is the recollement of category A(S) constructed from the known recollement of triangulated categories.
