On the zeroth-order general Randić index, variable sum exdeg index and trees having vertices with prescribed degree

Sohaib Khalid, Akbar Ali

The zeroth-order general Randić index (usually denoted by $R_{α}^{0}$ ) and variable sum exdeg index (denoted by $S E I_{a}$ ) of a graph $G$ are defined as $R_α^{0}(G)= \sum_{v\in V(G)}…
