In Section 1 of this paper, we investigate the finitely presented dimension of an essential
extension for a module, and obtain results concerning an essential extension of a torsion …

We define and studyco-Noetherian dimension of rings for which the injective envelopeof
simple modules have finite Krull-dimension. This is a Moritainvariant dimension that …

This note presents the definitions of homological dimensions of bounded complexes of
modules as proposed by the author in [3]. Somewhat different definitions have been …

In this paper, we compare Krull dimension, Gorenstein injective dimension and injective
dimension of a module in several cases. In fact, we establish some generalizations of the …

Let M be a finitely generated module over a regular local ring R. It is well known that the sum
of homological dimension and codimension of M is equal to the global dimension of R. For …

Assume that R is a commutative Noetherian ring with non-zero identity, a is an ideal of R, X
is an R-module, and t is a non-negative integer. In this paper, we present upper bounds for …

In this paper, we study injective dimension and Gorenstein injective dimension over local
ring homomorphisms. Some well-known results are generalized. For example, the Bass …

We study the relations between finitistic dimensions and restricted injective dimensions. Let
R be a ring and T a left R-module with A= End RT. If RT is selforthogonal, then we show that …
