本文研究了余极限范畴.利用余完备Abel范畴的定义,证明了余完备Abel范畴A的余极限范畴Acl是余完备的Abel范畴,并得到一类等价于模范畴的余极限范畴,从而推广了文献[9]中的一些结果.
In this article,we consider the colimit-categories.By using the definition of cocomplete abelian categories,we prove that such a colimit-category Acl of cocomplete abelian category A is a cocomplete abelian category and we get a class of colimit-categories which is equivalent to categories of modules.As a consequence,we generalize some results in[9].
