摘要
预包络和预覆盖的存在性问题是相对同调代数的核心内容.本文研究了在某些特定条件下模的预包络和预覆盖的存在性问题,得到了两个有关预覆盖和预包络的结果,并给出它们的应用.
The existence of preenvelope and precover is the key in the relative homological algebra. In this article the existence of preenvelope and precover in some specific conditions is studied. Two results of them are obtained and some applications are given.
