Zero divisors for matrices over commutative semirings
Asmaa M. Kanan
ABSTRACT: It is known that a square matrix A over a commutative ring R with identity is a left or right zero divisor in Mn(R) if and only if the determinant of A is a zero divisor in R. Additively inverse commutative semirings with zero 0 and identity 1 are a generalization of commutative rings with identity. In this paper, we present some results for matrices over this type of semiring which generalize the above result for matrices over commutative rings.
