This work contains some new and known results on modules over formal matrix rings. The
main results are presented with proofs. In ring theory, various matrix rings play an important …

In the present paper, we study formal matrix rings over a given ring and determinants of such
matrices. In Secs. 1–4, some general properties of formal matrix rings are presented. In …

This paper concerns the formal matrix ring Mn (R; s) over a ring R defined by a central
element s in R. Various basic properties of these rings are established; the isomorphism …

The first section of this paper contains the definition and some properties of generalized
matrix rings. Stenstrom [9] and Sakano [6] computed the ma:~ imal ring of quotients of a …

In this paper we carry out a systematic study of modules over a formal triangular matrix ring
[Formula: see text] Using the alternative description of right T-modules as triples (X, Y) f with …

In this paper we carry out a systematic study of various ring theoretic properties of formal
triangular matrix rings. Some definitive results are obtained on these rings concerning …

It is known that structural matrix rings pro-vide a natural passage from complete matrix rings
to upper and lower triangular matrix rings, and they often explain the peculiarities regarding …

We first tackle certain basic questions concerning the Invariant Basis Number (IBN) property
and the universal stably finite factor ring of a direct product of a family of rings. We then …
