The eccentric harmonic index of trees

The eccentric harmonic index of trees

AbstractTopological indices play an important role in mathematical chemistry, particularly in studies of quantitative structure property and quantitative structure activity relationships. The eccentric harmonic index of G is defined as [Formula: see text] where uv is an edge of G, e(u) is the eccent...
