本文研究了F-本质子模和F-多余子模.利用同调的方法,得到了F-本质与F-包络,F-多余与F-复盖之间的关系,另外还得到了F-本质子模,F-多余子模的相关性质,从而推广了文献[3,10]中的部分结果.
This article study F-essential submodules and F-superfluous submodules.By homological methods,we obtain the relations between F-essential map and F-envelope(between F-superfluous map and F-cover).Moreover,we show the relative properties of F-essential submodules and F-superfluous submodules,which generalize some results in [3,10].
