An Upper Bound on the Total Roman { 2 } -domination Number of Graphs with Minimum Degree Two
Journal of Combinatorial Mathematics and Combinatorial ComputingA total Roman \(\{2\}\)-dominating function on a graph \(G = (V,E)\) is a function \(f:V\rightarrow\{0,1,2\}\) with the properties that (i) for every vertex \({v}\in V\) with \(f({v})=0\), \(f(N({v}))\ge2\) and (ii) the set of vertices with \(f({v})>0 ...
