摘要
引入了S-Gorenstein平坦模,给出了S-Gorenstein平坦模的一些等价刻画,证明了S-Gorenstein平坦模关于直积封闭,并且证明了S-Gorenstein平坦模类是投射可解类当且仅当S-Gorenstein平坦模类关于扩张封闭.
S-Gorenstein flat modules are introduced,some equivalent characterizations of S-Gorenstein flat modules are given.It is proved that the class of S-Gorenstein flat modules is closed under direct products,and that the class of S-Gorenstein flat modules is projectively resolving if and only if it is closed under extensions.
