Abstract: Recently, in [18] Raikar et al. obtained explicit formulae for the first Zagreb index and coindex of k-splitting of generalized transformation graphs and their complement. The aim of this paper is to obtain explicit formulae for the second Zagreb index and coindex of k-splitting of generalized transformation graphs splk(Gab), and followed by this we also obtained analogous expressions for the complements of splk(Gab).
