Left prime weakly regular near-rings
In this paper we introduce the notion of left prime weakly regular, left primeweakly $ \pi $-regular and left prime pseudo $ \pi $-regular near-rings. We alsointroduce the concept of strong left prime weakly regular near-rings. We haveobtained conditions for a near-ring $ N $ to be left prime pseudo $ \pi $-regular.We have also obtained conditions for ...

RESULTS ON QUOTIENT NEAR-RINGS INVOLVING ADDITIVE MAPS [PDF]
We consider N to be a 3-prime field and P to be a prime ideal of N : In this paper, we studythe commutativity of the quotient ring N =P with left multipliers and derivations satisfying certainidentities on P, generalizing some well-known results in the ...

\((\alpha, \tau)\)-\(P\)-derivations on left near-rings
Summary: Suppose that \(\mathcal{N}\) is a near-ring and \(P\) is a 3-prime ideal of \(\mathcal{N}\). In this paper we introduce the notion of \((\alpha, \tau)\)-\(P\)-derivation in near-rings, we also study the structure of the quotient near-ring \(\mathcal{N}/P\) which satisfies certain algebraic identities involving \((\alpha, \tau)\)-\(P ...

Morphic elements in regular near-rings
We define morphic near-ring elements and study their behavior in regular near-rings. We show that the class of left morphic regular near-rings is prop?erly contained between the classes of left strongly regular and unit-regular near-rings.
