Abstract

The notion of majorization ordering was introduced by Hardy et al. [34] and is closely connected with the economic theory of disparity indices [2]. It is worth pointing out that previous uses of the majorization partial order in chemistry and a general overview are given in Klein [36]. Indeed, the degree sequence partial order has previously been studied from a chemical perspective in [37,62].

Abstract

We present a unified approach for localizing some relevant graph topological indices via majorization techniques. Through this method, old and new bounds are derived and numerical examples are provided, showing how former results in the literature could be improved.
