Distance-based graph invariants of trees and the Harary index


Introduced in 1947, theWiener indexW(T) = ∑ {u,v}⊆V(T) d(u, v) is one of themost thoroughly studied chemical indices. The extremal structures (in particular, trees with various constraints) that maximize or minimize theWiener index have been extensively investigated. The Harary indexH(T) = ∑ {u,v}⊆V(T) 1 d(u,v) , introduced in 1993, can be considered as the… (More)
