| چکیده | ||
| In this note, we point out several critical inaccuracies in a recent paper on the Sombor coindex of graphs [On Sombor coindex of graphs, Commun. Comb. Optim. 8 (2023), no. 3, 513–529.]. We identify fundamental errors in the main results and provide concrete counterexamples to refute them. | ||
