Abstract
This paper indicates alternative ways of deriving the main results of the recent paper [M. Zhang, B. Zhao, Extremal values of the Sombor index in tricyclic graphs, MATCH Commun. Math. Comput. Chem. 89 (2023) 741-758]. The graphs possessing minimum and maximum values of the reduced Sombor index are also characterized from the class of all tricyclic connected graphs of a given order.
期刊介绍：
MATCH Communications in Mathematical and in Computer Chemistry publishes papers of original research as well as reviews on chemically important mathematical results and non-routine applications of mathematical techniques to chemical problems. A paper acceptable for publication must contain non-trivial mathematics or communicate non-routine computer-based procedures AND have a clear connection to chemistry. Papers are published without any processing or publication charge.
