摘要

The annihilator graph of a non-commutative semiring S denoted by AG(S) is the graph whose vertice set is the set of all nonzero zero-divisors of S denoted by Z(S)~* = Z(S){0} and two distinct vertices are adjacent if and only if either l · ann(xy) ≠ l · ann(x) ∪ l · ann(y), l · ann(yx) ≠ l · ann(x) ∪ l · ann(y), r · ann(xy) ≠ r · ann(x) ∪ r · ann(y), or r · ann(yx) ≠ r · ann(x) ∪ r · ann(y), where l · ann(a) = {s ∈ S|sa = 0} and r · ann(a) = {s ∈ S|as = 0} for a ∈ Z(S). In this paper, we show that AG(S) is connected with diameter at most two.
