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+00:00Copyright (c) 2025 Ting Li, Bingjun lihttps://rajpub.com/index.php/jam/article/view/9697Solving cubic and quartic equations by means of Vieta's formulas2024-12-25T11:31:54+00:00Miloš Čojanovićmcojanovic@yahoo.com<p>In this paper, we will prove that with the use of Vieta's formulas, it is possible to apply a unified method in solving equations of the third and fourth degree.</p>2025-02-04T00:00:00+00:00Copyright (c) 2025 Miloš Čojanović
