Abstract
Let G be a (p,q) graph. A mapping f : V (G) → {0, 1, 2} is called 3-product cordial labeling if |v????(i) − v???? (j)| ≤ 1 and |e???? (i) − e???? (j)| ≤ 1 for any i, j ∈ {0, 1, 2},where v???? (i) denotes the number of vertices labeled with i, e???? (i) denotes the number of edges xy with ????(x)????(y) ≡ i(mod3). A graph with 3-product cordial labeling is called 3-product cordial graph. In this paper we investigate the 3-product cordial behavior of alternate triangular snake, double alternate triangular snake and triangular snake graphs.
