Precover completing domains and approximations
In this paper, we introduce an X-precover completing domain X− 1 (L), with L being a class
of modules and not necessarily a single module, and then investigate when every module in …

Some homological characterizations of regular rings
J Ahsan, AS Ibrahim - Communications in Algebra, 1982 - Taylor & Francis
A ring R is regular if for each a in R there exists an x in R such that a= axa. Regular rings
were introduced by von Neumann in [26], where he showed that the set of principal right …

Weakly-projective covers for left R-modules
A Esterhuyse - Suid-Afrikaanse Tydskrif vir …, 1989 - journals.satnt.aosis.co.za
All the necessary definitions are given in the introduction. Since it is not true that every left R-
module possesses a projective cover, as is the case with injective hulls, it is the aim of this …
