Abstract. An injective function f : V (G) → {l1, l2, . . . , ln}, where lj is the jth Lucas number (j = 1, 2, . . . , n) is said to be Lucas product cordial labeling if the induced function f∗ : E(G) → {0, 1} defined by f ∗(uv) = (f(u)f(v)) (mod 2) satisfies the condition |ef∗ (0) − ef∗ (1)| ≤ 1. A graph which admits Lucas product cordial labeling is called Lucas product cordial graph. In this paper, we determined the Lucas Product Cordial Labeling of Quadrilateral Snake Graph Qn, Cycle Quadrilateral Snake Graph CQn, and Alternate Triangular Snake Graph A(Tn).
