On the Unified Extremal Results on Distance-Based Bond Additive Indices on Trees
Szeged-type bond additive indices are a class of distance-based topological indices defined by counting the vertices or edges that are closer to the end vertices of an edge. Important members of this family include the Szeged index, Mostar index, PI index, SPI index, and the Szeged–Sombor index, together with their cor...
