摘要
本文研究了右IF-环的性质,证明出环R是右IF-环当且仅当R是左凝聚环,并且是平坦模;由此证明出右IF-环与左GQF-环是等价的,其次应用右IF-环研究了凝聚环的挠理论性质,证明出凝聚环与T-凝聚环的关系。
This paper discusses some properties of right IF-rings,proves R is a right IF-ringif and only if it is a left coherent ring and is a flat module;thus proves right IF-rings andleft GQF-rings are equivatent secondly,studies some torsion theory properties of the coherentrings by right IF-rings,proves the relation between coherent rings andr r-coherent rings。
