Pentagonal pyramidal graceful number
pentagonal pyramidal graceful graphs
pentagonal pyramidal graceful labeling - Opis:
- Numbers of the form (n^(2 ) (n+1))/2 for all n≥1 are called pentagonal pyramidal numbers. Let G be a graph with p vertices and q edges. Let Ψ : V(G) →{0, 1, 2… M_r} where M_r is the r^th pentagonal pyramidal number be an injective function. Define the function Ψ*:E(G) →{1,6,18,.., M_r} such that Ψ *(uv) = |Ψ (u)- Ψ (v)| for all edges uvϵE(G). If Ψ*(E (G)) is a sequence of distinct consecutive pentagonal pyramidal numbers {M_1,M_2, …, M_r}, then the function Ψ is said to be pentagonal pyramidal graceful labeling and the graph which admits such a labeling is called a pentagonal pyramidal graceful graph. In this paper, some special graceful labeling results of pentagonal pyramidal graceful graphs is studied.
