The existence of envelopes
Copure injective resolutions, flat resolvents and dimensions
Edgar E. Enochs, Jenda M. G. Overtoun (1993)
Commentationes Mathematicae Universitatis Carolinae
Similarity:
In this paper, we show the existence of copure injective preenvelopes over noetherian rings and copure flat preenvelopes over commutative artinian rings. We use this to characterize -Gorenstein rings. As a consequence, if the full subcategory of strongly copure injective (respectively flat) modules over a left and right noetherian ring has cokernels (respectively kernels), then is -Gorenstein.
Characterizations of some rings with -projective, -(FP)-injective and -flat modules

Czechoslovak Mathematical Journal
Similarity:
Let be a commutative ring and a semidualizing -module. We investigate the relations between -flat modules and -FP-injective modules and use these modules and their character modules to characterize some rings, including artinian, noetherian and coherent rings.
