On topological indices of carbon nanocones and nanotori

Abstract

Abstract Let G be a graph with n vertices and d i is the degree of its i th vertex ( d i is the degree of v i ). In this article, we compute the redefined first Zagreb index, redefined second Zagreb index, redefined third Zagreb index, augmented Zagreb index of graphs carbon nanocones CNC k [ n ], and nanotori [ C 4 C 6 C 8 ( p , q )]. Also, compute the multiplicative redefined first Zagreb index, multiplicative redefined second Zagreb index, multiplicative redefined third Zagreb index, multiplicative augmented Zagreb index of carbon nanocones CNC k [ n ], and nanotori [ C 4 C 6 C 8 ( p , q )].
