Webrings are precisely those rings where all modules have Gorenstein flat-cotorsion dimension at most zero. In the second, we show that Quasi-Frobenius rings are those rings where all modules are Gorenstein flat-cotorsion. Further, we show in Theorems 4.5 and 4.9 that under assumptions of finite finitistic dimensions, rings of finite Gorenstein ...
