Edge removal-graphs of weak domination
Qiong Fan · 2008
The bondage number is an important area in the research of the domination number of a graph.In some degree,it reflects the sensitivity of the domination number of edges of a graph,and it is very important to research ER-critical graphs.This paper investigated γ+w-ER-critical graphs and γ-w-ER-critical graphs,and gave out sufficient and necessary condition for two-degree graphs to be γ+w-ER-critical and γ-w-ER-critical,respectively.
