摘要
用H(F)表示F-Gorenstein平坦左 R-模类.在一般环上引入模的F-Gorenstein平坦维数,并给出F-Gorenstein平坦维数的一些等价刻画.作为应用,证明若每个模的F-Gorenstein平坦维数不超过1,则(H(F),H(F)⊥)是完备遗传的余挠对.
Denote the class of F-Gorenstein flat R-modules by H ( F ). Some descriptions of F-Gorenstein flat dimension are given for an arbitrary ring. As an application, it is proved that if the F-Gorenstein flat dimension of all R-modules is not more than 1, then the pair ( H ( F ), H ( F )⊥) forms a complete and hereditary cotorsion pair.
