Our focus centers on exploring the p-Sombor index of unicyclic graphs, speciffcally addressing graphs with a predetermined girth. We determine the ffrst four smallest p-Sombor index and identifying the corresponding graphs that achieve these extremes.</p> 2025-03-28T00:00:00+00:00 Copyright (c) 2025 Ting Li, Bingjun li
