Graceful labeling of triangular extension of complete bipartite graph
Sarbari Mitra, Soumya Bhoumik · Electronic Journal of Graph Theory and Applications · 2019
For positive integers m , n , K m , n represents the complete bipartite graph. We name the graph G = K m , n ⊙ K 2 as triangular extension of complete bipartite graph K m , n , since there is a triangle hanging from every vertex of K m , n . In this paper we show that G is graceful when m = n = 2ℓ , for any integer ℓ .
