Description:
Let G1 and G2 be copies of a graph G, and let f : V (G1) → V (G2) be a function. Then a functigraph C(G, f) = (V, E) is a generalization of a permutation graph, where V = V (G1) ∪ V (G2) and E = E(G1) ∪ E(G2) ∪ {uv : u ∈ V (G1), v ∈ V (G2), v = f(u)}. In this paper, we study colorability and planarity of functigraphs.
