Rezumat

Let G be a graph with vertex set V (G) and edge set E(G). The first and second multiplicative Zagreb co-indices are defined as: Y1 (G) =Yuv/∈E(G) [dG(u) dG(v)] , Y2 (G) =Yuv /∈E(G) [dG(u)dG(v)], respectively, where dG(u) is the degree of the vertex u of G. The aim of this paper is to investigate the multiplicative Zagreb co-indices of the subdivision graphs of tadpole graphs and wheel graphs
