On Reduced Zagreb Indices of Polycyclic Aromatic Hydrocarbons and Benzenoid Systems

Abstract

In this paper, we introduce the reduced modified fi rst Zagreb index, reduced inverse degree index, reduced zeroth-order Randi ć index, reduced F-index and generalized reduced first Zagreb index of a graph. Also we determine these indices for polycyclic aromatic hydrocarbons and jagged rectang le benzenoid systems.
