解釋
自由代數-
Using universal property, we can define general ( pre ) cover and ( pre ) envelope, such as gorenstein injective ( projective or flat ) ( pre ) cover and ( pre ) envelope, 5 - torsion free ( pre ) cover etc. in a word, problems on ( pre ) over and ( pre ) envelope have aroused considerable debate in the academic circle, which embodies flexible use of tools of homological algebra in studying categories of rings and modules
而且利用泛性我們又可定義更廣泛意義上的包、蓋問題,例如: gorenstin內射(平坦、投射)包(蓋) , s -無撓預蓋,等等。用這類比內射(平坦、投射)更廣泛意義上的特殊模又能刻畫一些環。總之,包、蓋問題是當今非常活躍的研究課題,體現了同調代數在環模範疇研究中靈活運用。 -
