On Super Edge Local Antimagic Total Labeling By Using An Edge Antimagic Vertex Labeling Technique
... However, definition of a proper coloring, the adjacent edges can not be assigned by the same colors. Therefore, we need to re-assign a color to the adjacent edges. By using Lemma 3.2, let 𝑊 = *(𝑤 , 𝛼 ); 𝑤 ∈ ...
