Frobenius functors and Gorenstein flat dimensions
J Hu, H Li, Y Geng, D Zhang - Communications in Algebra, 2020 - Taylor & Francis
We prove that if the Frobenius functor F (from the category of left R-modules to the category
of left S-modules) is faithful, then for any R-module X, the Gorenstein flat dimension of X is …
