Vertex-Magic Total Labelings,A one-to-one map . from . onto the integers . is a . if there is a constant . so that for every vertex ., . where the sum is over all vertices . adjacent to .. So the magic requirement is wt(.) = . for all .. The constant . is called the . for λ. Again, a graph with a vertex-magic total labeling will be called ..
