More on the weakly 2-prime ideals of commutative rings

Let R be a commutative ring with a nonzero identity. In this paper, we introduce the concept of weakly 2-prime ideal which is a generalization of 2-prime ideal and both are generalizations of prime ideals. A proper ideal I of R is called weakly 2-prime ideal if whenever a, b E R with 0 not equal ab is an element of I, then a (2) or b (2) lies in I. A number results concerning weakly 2-prime ideals are given. Furthermore, we characterize the valuation domain and the rings over which every weakly 2-prime ideal is 2-prime and rings over which V every weakly 2-prime ideal is semi-primary (i.e root I is a prime ideal). We study the transfer the notion of weakly 2-prime ideal to amalgamted algebras along an ideal A (sic)(f) J.
