Let R be a commutative ring with identity and A(R) be the set of ideals with
nonzero annihilator. The annihilating-ideal graph of R is defined as the
graph AG(R) with the vertex set A(R)* = A(R)\{0} and two distinct vertices I
and J are adjacent if and only if IJ = 0. In this paper, we study the
domination number of AG(R) and some connections between the domination
numbers of annihilating-ideal graphs and zero-divisor graphs are given.
Keywords: annihilating-ideal graph, zero-divisor graph, domination number, minimal prime ideal
