Exact Decompositions and Zero-Divisor Graphs
摘要
A pair of zero-divisors are exact if one generates the annihilator of the other. For some rings the well-studied zero-divisor graph is sufficient for identifying all exact pairs, which is displayed in the exact zero-divisor subgraph. We initiate the study of constructing zero-divisor graphs with only the graphical structure of exact zero-divisor subgraphs and provide results for 1-component and 2-component cases.
