Two New Types of Rings Constructed from Quasiprime Ideals

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2011
Keigher showed that quasi-prime ideals in differential commutative rings are analogues of prime ideals in commutative rings. In that direction, he introduced and studied new types of differential rings using quasi-prime ideals of a differential ring.

Neutrosophic Rings I [PDF]

open access: yes, 2011
In this paper, we present some elementary properties of neutrosophic rings. The structure of neutrosophic polynomial rings is also presented. We provide answers to the questions raised by Vasantha Kandasamy and Florentin Smarandache in [1] concerning ...

Formal Groups and Hopf Algebras over Discrete Rings [PDF]

open access: yes, 1974
A theory of formal schemes and groups over abitrary rings is presented. The flat formal schemes in this theory have coalgebras of distributions which behave in the usual way. Frobenius and Verschiebung maps are studied.

Upper Cohen-Macaulay Dimension [PDF]

open access: yes, 2004
In this paper, we define a homological invariant for finitely generated modules over a commutative noetherian local ring, which we call upper Cohen-Macaulay dimension.

Isomorphism of generalized triangular matrix-rings and recovery of tiles

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2003
We prove an isomorphism theorem for generalized triangular matrix-rings, over rings having only the idempotents 0and 1, in particular, over indecomposable commutative rings or over local rings (not necessarily commutative).

Continuous functions with compact support

open access: yesApplied General Topology, 2004
The main aim of this paper is to investigate a subring of the ring of continuous functions on a topological space X with values in a linearly ordered field F equipped with its order topology, namely the ring of continuous functions with compact support ...

On the Commutative Rings with At Most Two Proper Subrings

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2016
The commutative rings with exactly two proper (unital) subrings are characterized. An initial step involves the description of the commutative rings having only one proper subring.
