Multiplicative generalized derivations on ideals in semiprime rings

Mathematica Slovaca, 2016
Abstract Let R be a ring and I is a nonzero ideal of R. A mapping F:R → R is called a multiplicative generalized derivation if there exists a mapping g:R → R such that F(xy) = F(x)y + xg(y), for all x, y ∈ R. In the present paper, we shall prove that R contains a nonzero central ideal if any one of the following holds:

ON GRADED SEMIPRIME AND GRADED WEAKLY SEMIPRIME IDEALS

2013
Let G be an arbitrary group with identity e and let R be a G-graded ring. In this paper, we define graded semiprime ideals of a commutative G-graded ring with nonzero identity and we give a number of results concerning such ideals. Also, we extend some results of graded semiprime ideals to graded weakly semiprime ideals.

Semiprime rings with D.C.C. on principal bi-ideals

Periodica Mathematica Hungarica, 1986
The main result of the paper is the equivalence of the following conditions: 1) A is a semiprime ring with d.c.c. on bi-ideals of the form aAb, a,b\(\in A\); 2) A is semiprime with d.c.c. on principal bi-ideals; 3) A is semiprime and A coincides with its right socle; 4) Every finite subset of A can be embedded in a bi-ideal of A which is semiprime ...

Prime and Semiprime Ideals in Semirings

1999
As in the case of rings, an ideal I of a semiring R is prime if and only if whenever H K ⊆ I, for ideals H and K of R, we must have either H ⊆ I or K ⊆ I. The set of all prime ideals of a semiring R is called the spectrum of R and will be denoted by spec(R).
