关于 GC-平坦维数
On GC-flat dimension
摘要
Abstract
The cover GC-flat dimension of R-modules over an associative ring is introduced. It is characterized that the class of GC-flat modules is projectively resolving. We show that the GC-flat dimension of R-modules is less than or equal to its cover GC-flat dimension,and they are equivalent over a GFC closed ring.关键词
