摘要 令Χ是一个包含投射模的模类,研究了Gorenstein Χ-投射模和Gorenstein Χ-投射维数,给出了它们的一些性质.证明了Gorenstein Χ-投射合冲模就是投射合冲模. Let Χ be a class of modules that contains all projective modules.Gorenstein Χ-projective modules and Gorenstein Χ-projective dimension are investigated in this paper,and some of their properties are given.In particular,it is proved that Gorenstein Χ-projective syzygy modules are eΧactly projective syzygy modules.
