Abstract

Recently two new degree concepts have been defined in graph theory: ev-degree and ve-degree. Also the evdegree and ve-degree Zagreb and Randić indices have been defined very recently as parallel of the classical
definitions of Zagreb and Randić indices. It was shown that ev-degree and ve-degree topological indices can be
used as possible tools in QSPR researches . In this paper we define the ve-degree and ev-degree Narumi–Katayama
indices, investigate the predicting power of these novel indices and extremal graphs with respect to these novel
topological indices. Also we give some basic mathematical properties of ev-degree and ve-degree NarumiKatayama and Zagreb indices.
