| Abstract | ||
| A simple graph G = (V, E) is said to be k-Zumkeller graph if there is an injective function f from the vertices of G to the natural numbers N such that when each edge xy ∈ E is assigned the label f(x)f(y), the resulting edge labels are k distinct Zumkeller numbers. In this paper, we show that the super subdivision of path, cycle, comb, ladder, crown, circular ladder, planar grid and prism are k-Zumkeller graphs. | ||
