Modified eccentric connectivity polynomial of some graph operations

摘要

The modified eccentricity connectivity polynomial of a connected graph G is defined as Ξ(G; x)=Σ _(u∈V(G))d _G(u)x ~(ε′)G ~((u)), where ε′ _G(u)=Σ _(v∈NG(u))εG(u)and d _G(u) is the degree of u in G. In this paper modified eccentric connectivity polynomial is computed for several classes of composite graphs.
