摘要
引进了GN-环,FGT-内射模,FGT-内射维数。讨论GN-环的特征性质和GN-环上模的对偶性,推广J.P.Jans的一些重要结论,给出右整体FGT-内射维数为0的环类。
Some new concepts , such as GN - ring , FGT - injective modules , FGT - injective dimension, are introduced; some characteristic properties of GN-ring are given; and the duality of modules over GN-ring are discussed , some theorems of J. P. Jams are generalized , meanwhile, the characteristic of rings over which the right FGT-injective dimension is equal to zero is also given.
