Abstract

Lanzhou invariant is one of the important topological invariant which is better than the existing ones to predicting a chemically relevant property. In this paper, we study the Lanzhou invariant for four new operation of graphs which are related to some special well-known graphs which is introduced by Sarkar et al. [5] in 2017.

Keywords and Phrases

Graph invariant, join, subdivision, total graph.
