| Abstract: | By using the properties of the zeroth-order general Randic index and analyzing the structure of the quasi-tree graphs, the extremal values of zeroth-order general Randic indices of quasi-tree graphs with perfect matchings and p pendant vertices are determined. Furthermore, the corresponding extremal quasi-tree graphs are identified. |

| Keywords: | zeroth-order general Randic index quasi-tree graph perfect matching pendant vertex |
