摘要 引进了n-FC模的概念,给出了n-FC模的刻画,并利用余挠理论进一步研究了n-FC模的性质,证明了R是右n-凝聚环且RR是n-FC模当且仅当每个左R-模有单的Fn-预包络当且仅当(FCn,FC⊥n)是perfect余绕理论. The concept of n-FC modules is introduced.Some basic characterizations of n-FC mod-ules are given,and some properties of n-FC modules are investigated by cotorsion theory.It is proved that R is right n-coherent and RR is n-FC if and only if very left R-module has a monic Fn-preenvelope ifand only if(FCn,FC⊥n) is a perfect cotorsion theory.
