摘要：
One important topic in chemical graph theory is the extremal value problem of vertex-degree-based topological indices over chemical trees. It is our main goal in this paper to unify many of these results in one general theorem which captures the common properties which are essential. We also apply our results to obtain extremal values of exponential vertex-degree-based topological indices over chemical trees. © 2020
