Inverse Roman Domination in Graphs

ZHANG Li-xian;LU Xin-zhong;School of Mathematics.Zhejiang Normal University;  
In this paper,the concept of inverse roman domination number is introduced.The properties of inverse roman domination number are studied by using the method and the conclusion of roman domination number and then the values of roman domination number and inverse roman domination number are obtained for some special graphs such as paths,cycles,complete graphs.Thereby,this conclusion of the special graphs can be generalized to any connected n(n≥3)-vertex graphs and its lower and upper bound are achieved.
