Let cp be a ring homomorphism from a ring R to a ring Q. If Q is flat as a right R-module and
q is a ring epimorphism, we say that QR is a flat epimorphism. If Q is projective with respect …

Our aim here is to give a structure theorem for flat extensions of a commutative noetherian
ring R-that is, those R-algebras which are flat when viewed as R-modules-which arc …

Let $ R $ be a ring with identity and $ M $ a two-sided $ R $-module. It is shown that every
right quotient ring in the sense of Gabriel of the trivial extension of $ R $ by $ M $ is a trivial …

Conditions for the endomorphism ring of a (finitely generated) projective module to be left
(semi) hereditary have been studied in several papers ([2],[7],[8]). In [2] and [8] it is shown …

Given a homological ring epimorphism from a ring R to another ring S, we show that if the
left R-module S has a finite-type resolution, then the algebraic K-group K n (R) of R splits as …
