摘要
研究了弱d-Koszul模范畴保持满同态核的条件,运用同调代数的相关知识,得到了一个充分条件:若对任意的ik,≥0J,kΩi(K)=Ωi(K)∩JkΩi(M),则弱d-Koszul模范畴在满同态的核下是封闭的.
It was studied the conditions for the category of weakly d-Koszul modules to be closed under kernels of epimorphisms.By using some related knowledge of homological algebra,a sufficient condition was obtained: supposed J^kΩ^i(K)=Ω^i(K)∩J^kΩ^i(M) for any i,k≥0,then the category of weakly d-Koszul modules would be closed under kernels of epimorphisms.
