On the Relationships between Topological Coindices
Abstract: The equations for a graph G having n vertices and m edges with (M_1 ) ?(G),M_1(G ?), (M_1 ) ?(G ?), (M_2 ) ?(G), M_2(G ?), (M_2 ) ?(G ?) and F ?(G) were established by Gutman et al.[1]. In this paper the relationships between topological coindices and coindices of complement graphs of Dutch windmill, wheel and helm graph are studied.
Keywords: Complement graph, Dutch windmill graph, forgotten coindex, helm graph, multiplicative Zagreb coindex, wheel graph, Y- coindex, Zagreb coindex
