ON GI-FLAT MODULES AND DIMENSIONS
Let R be a ring. A right R-module M is called GI-flat if <TEX>$Tor^R_1(M,G)=0$</TEX> for every Gorenstein injective left R-module G. It is shown that GI-flat modules lie strictly between flat modules and copure flat modules. Suppose R is an <TEX>$n$</TEX>-FC ring, we prove that a finitely presented right R-module …
