On realizing zero-divisor graphs of po-semirings
arXiv:1106.0350
Abstract
In this paper, we determine bipartite graphs and complete graphs with horns, which are realizable as zero-divisor graphs of po-semirings. As applications, we classify commutative rings whose annihilating-ideal graph are either bipartite graphs or complete graphs with horns.
