Abstract:In a recent work [Chem. Phys. Lett. 333 (2001) 319-321] Nikolić, Trinajstić, and Randie put forward a novel modification ▫$^m$▫W of the Wiener index. We now show that ▫$^m$▫W possesses the basic properties required by a topological index to be acceptable as a measure of the extent of branching of the carbon-atom skeleton of the respective molecule (and therefore to be a structure-descriptor, potentially applicable in QSPR and QSAR studies). In particular, if ▫$T_n$▫ is any n-vertex tree, different from the n-vertex path ▫$P_n$▫ and the n-vertex star ▫$S_n$▫, then mw(Pn) < mW(Tn) < mW(Sn). We also show how the concept of the modified Wiener index can be extended to weighted molecular graphs.

Title:Potvrda modifikacije Wienerova indeksa
Abstract:U nedavnom su članku (Chem. Phys. Lett. 333 (2001) 319–321) Nikolić, Trinajstić i Randić predložili novu modifikaciju, ▫$^m$▫W, Wienerova indeksa. U ovom je članku pokazano da ▫$^m$▫W posjeduje osnovna svojstva koja mora imati topologijski indeks da bi bio prihvatljiv kao mjera grananja ugljikova kostura pojedine molekule (pa da bi bio primjenjiv u QSPR i QSAR modeliranju). Ako je ▫$T_n$▫ bilo koje stablo s n čvorova, koje se razlikuje od staze ▫$P_n$▫ s n čvorova i zvijezde ▫$S_n$▫ s n čvorova, tada je mw(Pn) < mW(Tn) < mW(Sn). Također je pokazano da se koncepcija o modificiranom Wienerovu indeksu može proširiti na vagane molekulske grafove.
