Abstract
Among the 16 expressions derived in the recent paper [Int. J. Quantum Chem.2020,120(6), e26082] for calculating certain degree-based topological indices of the molecular graphs of carbon nanocones and nanotori, 12 expressions contain some mistakes, and the remaining 4 follow from an already existing general expression. In this note, the correct versions of the aforementioned erroneous expressions are obtained.
