Two modulo three sum graph
Two modulo three sum labeling - Opis:
- Let G = (V, E) be a graph with p vertices and q edges is said to be a two modulo three sum graph if there is an injective function f from V(G) to { a∶0≤a≤3q-1 and either a≡0(mod 3) or a≡2(mod 3)} where q is the number of edges of G and such that finduces a bijectionf^* from E(G) to {a∶2≤a≤3q-1 and a≡2(mod 3)} given byf^* (uv)=f(u)+f(v)and the function f is called two modulo three sum labeling of G. In this paper, we introduce an analog of sum labeling known as two modulo three sum labeling and we define two modulo three sum labeling of some tree related graphs. Also we prove that split star, mirror path graph, complete bipartite graph and C_4 ʘ〖nK〗_1 are two modulo three sum graphs.
