Given a graph G, a function of assigning distinct labels to such that , ∀ is an antimagic labeling of G where indicates the vertex sum obtained by summing up all the labels assigned to the edges incident on the vertex a. Let G, , be connected graphs such that . A new graph is constructed from G, , by adding all possible edges between the end vertices of and , . The resulting graph is called the generalized edge corona of G and which is denoted as . We prove G ⋄ is antimagic under certain conditions using an algorithmic approach where G has only one vertex of maximum degree three (excluding spider graphs containing uneven legs) and , .
Keywords: Antimagic labeling; Generalized edge corona graphs; Graph labeling; Pan graphs; Spider graphs.
