A path of maximum length in a connected graph G(V, E) is called a detour path between u and v, and is denoted by ∂(u, v). For any vertex u in a connected graph G, we define the length of a detour path in a graph G is called the detour number of G, and is denoted by ∂(G). i.e. ∂(G) = max { ∂(u): u ∈V(G) }. In this paper we study on several bounds on graph-theoretic parameters in terms of the detour number.

Abstract


A path of maximum length in a connected graph G(V, E) is called a detour path between u and v, and is denoted by ∂(u, v). For any vertex u in a connected graph G, we define the length of a detour path in a graph G is called the detour number of G, and is denoted by ∂(G). i.e. ∂(G) = max { ∂(u): u ∈V(G) }. In this paper we study on several bounds on graph-theoretic parameters in terms of the detour number.
