exact sequence of morphisms 中文意思是什麼
exact sequence of morphisms
解釋
射的正合序列-
In the second chapter, we attain this goal by another route. collecting all short exact sequence and the morphisms among them, we get a new category, call the short exact sequences category crm. we define a global dimension attached to the original ring r from the view of the short exact sequences category cr. m, named the exact projective dimension
在第二章中我們將通過另一種方法,也就是考察所有的短正合列以及短正合列之間的態射,我們得到一個新的范疇,通過對這個范疇(我們稱之為短正合列范疇c _ rm )的一些基本性質的考察,我們定義出與環r相關的同調維數,我們稱它為正合投射維數。
