On Polynomials Derived from Topological Indices of Special Graphs

Polynomials associated with topological indices are defined from graph-based indices with their coefficients and exponents derived from these values. This paper presents formulae for such polynomials for cycle Cn, wheel Wn, path Pn, complete graph Kn and complete bipartite graph Km,n. It is further shown that a graph is a closed path if and only if...
