In this paper, by a left QF-3 ring we shall always understand a ring with a (unique) minimal
faithful left module, and by a QF-3 ring we mean a ring which is both left and right QF-3 …

Semiartinian right V-rings, which we call right SV-rings, form a special class of Von
Neumann regular rings. We characterize these rings by the fact that every factor ring imbeds …

This paper consists of three parts. The first is devoted to investigating the equivalence and
left-right symmetry of several conditions known to characterize finite dimensional algebras …

H-rings and Co-H-rings have been defined by K. Oshiro in [9]. A ring R is a right H-ring (Co-
H-ring) iff every injective (projective) right R-module is lifting (extending). A right H-ring or a …

The notion of QF-3 rings was introduced originally by RM Thrall [13] for the case of finite
dimensional algebras over a field. Recently this notion has been extended to the case of …

A ring R (associative with identity) is called right ℵ-QF 3 if it has a faithful right ideal which is
a direct sum of a family of injective envelopes of pairwise non-isomorphic simple right R …

In [ll] Kato introduced a notion of dominant modules: Let A be a ring, W, a faithful, finitely
generated projective module, and B= End (W,) the endomorphism ring of W,. Then he called …

Colby and Rutter [6] proved that a ring R contains an essential left socle and an essential
right socle and has a two sided semi-simple maximal (complete) quotient ring if and only if R …
