New composition of graphs and their Wiener Indices

Abstract

Abstract In this paper, we define new graph operations F -composition F ( G )[ H ], where F ( G ) be one of the symbols S ( G ) ,M ( G ) ,Q ( G ) ,T ( G ),Λ( G ),Λ[ G ] ,D 2 ( G ) ,D 2 [ G ]. Further, we give some results for the Wiener indices of the these graph operations.
