Vector Basis S-Cordial Labeling of Graphs
Abstract
Let G be a (p, q) graph. Let V be an inner product space with basis S. We denote the inner product of the vectors x and y by <x, y>. Let φ: V(G)→S be a function. For edge uv assign the label <ϕ(u), ϕ(v)>. Then ϕ is called a vector basis S-cordial labeling of G if |φx−φy|≤1 and |γi-γj|≤1 where φx denotes the number of vertices labeled with the vector x and γi denotes the number of edges labeled with the scalar i. A graph which admits a vector basis S-cordial labeling is called a vector basis S-cordial graph. In this paper, we investigate the vector basis S-cordial labeling behavior of certain standard graphs like path, cycle, complete graph and star graph.
