Abstract

In this article, we provide new formulas to compute the reduced reciprocal randić index, Arithmetic geometric₁ index, SK index, SK ₁ index, SK ₂ index, edge version of the first zagreb index, sum connectivity index, general sum connectivity index, and the forgotten index using the M-polynomial and finding these topological indices for a boron triangular nanotube. We also elaborate the results with graphical representations.

Keywords: M-polynomial; boron triangular nanotube; chemical graph theory; graph; topological indices.
