An edge labeling of a connected graph G = (V, E) is said to be local antimagic if it is a Bijection f : E → {1, …,|E|} such that for any pair of adjacent vertices x and y, f +(x) ≠ f +(y), where the induced vertex label f +(x) = Σf(e), with e ranging over all the edges incident to x. The local antim...
