摘要 设A是一个Abelian范畴.定义了Cartan Eilenberg(余)真分解(简称为CE-(余)真分解),给出了短正合列中CE-(余)真分解的构造及与函子Hom_A(-,-)的关系. Let Abe an Abelian category.This paper defines the Cartan Eilenberg-(co)proper resolution(referred to as CE-(co)proper resolution),provides a method to construct a CE-(co)proper resolution in a short exact sequence,and gives some relationship between it and the functor HomA(-,-).
