An ??-graph of G is newly defined class of graph that can be constructed by the replication of G in a particular fashion. In this Thesis, we study topological indices of line graph of ??-graph where the ??-graphs are produced by very known graphs which is ladder graph its extension triangular ladder graph, fan graph, friendship graph, circle graph, path graph.enDr. Yousaf Habibfa8MATHEMATICSDepartment of MathematicsThesis
