ON A GENERALIZATION OF THE MCCOY CONDITION [PDF]
We in this note consider a new concept, so called …-McCoy, which unifies McCoy rings and IFP rings. The classes of McCoy rings and IFP rings do not contain full matrix rings and upper (lower) triangular matrix rings, but the class of …-McCoy rings contain upper (lower) trian- gular matrix rings and many kinds of full matrix rings.

Semi-commutativity and the McCoy condition
A ring \(R\) is called `right McCoy' if it satisfies: whenever \(f(x)g(x)=0\) in \(R[X]\) for non-zero polynomials \(f(x)\) and \(g(x)\), then there is a non-zero \(r\in R\) with \(f(x)r=0\). \(R\) is called a `McCoy ring' if it is both left and right McCoy. It is known that any commutative ring and any reduced ring is a McCoy ring.

On modules related to McCoy modules
In this paper, we first investigate the relationships between the McCoy module and related modules based on their relationships in rings. After that, we improve some properties of McCoy modules and introduce ZPZC modules which extend the notion of McCoy ...

MCCOY CONDITION ON IDEALS OF COEFFICIENTS [PDF]
We continue the study of McCoy condition to analyze zero- dividing polynomials for the constant annihilators in the ideals generated by the coefficients. In the process we introduce the concept ofideal- - McCoy rings, extending known results related to McCoy condition. It is shown that the class of ideal- -McCoy rings contains both strongly McCoy rings

A Liouville type theorem for p-Laplace equations
In this note we study solutions defined on the whole space R^N for the p-Laplace equation $$ \hbox{div}(| \nabla u|^{p-2}\nabla u)+f(u)=0. $$ Under an appropriate condition on the growth of f, which is weaker than conditions previously considered ...

Composite Hurwitz Rings as PF-Rings and PP-Rings
Let R ⊆ T be an extension of commutative rings with identity and H ( R , T ) (respectively, h ( R , T ) ) the composite Hurwitz series ring (respectively, composite Hurwitz polynomial ring).

The aim of the study was to evaluate the laryngoscopes Macintosh, Miller, McCoy, Intubrite, VieScope and I-View in simulated out-of-hospital conditions when used by people without clinical experience, and to choose the one that, in the case of failure of the first intubation (FI), gives the highest probability of successful second (SI) or third (TI ...
