In this paper, we study the existence of β₯ -envelopes, -envelopes, β₯ -envelopes, -covers, and -covers where and denote the classes of modules of injective and projective dimension less than or equal to a natural number n, respectively. We prove that over any ring R, special β₯ -preenvelopes and speci

In this note, we find conditions under which it is possible to prove the existence of relative injective covers of any module over the fixed ring R G by means of relative injective covers of modules over the base ring R. The same problem is treated for flat covers.
Galois theory for normal unramified coverings of finite irregular graphs (which may have multiedges and loops) is developed. Using Galois theory we provide a construction of intermediate coverings which generalizes the classical Cayley and Schreier graph constructions. Three different analogues of A
A left and right Noetherian ring R is called Gorenstein if both R and R have R R finite injective dimensions. These rings were studied by Bass for the commutative case and Iwanaga for the noncommutative case. In this paper, we define Gorenstein flat modules over a Gorenstein ring. These modules are
