For a graph G,P(G,λ)denotes the chromatic polynomial of G. Two graphs G and H are said to be chromatically equivalent,denoted by G-H,if P(G,λ)=p(H,λ). Let[G]
The paper introduces Hermite-Fejér type (Hermite type) interpolation of higher order denoted by Smn (f)(Snmn (f)), and gives some basic properties includin
