Abstract:In the paper we study maximal values of Balaban and sum-Balaban index, and correct some results appearing in the literature which are only partially correct. Henceforth, we were able to solve a conjecture of M. Aouchiche, G. Caporossi and P. Hansen regarding the comparison of Balaban and Randić index. In addition, we showed that for every k and large enough n, the first k graphs of order n with the largest value of Balaban index are trees. We conclude the paper with a result about the accumulation points of sum-Balaban index.

Abstract:V članku preučujemo maksimalne vrednosti Balabanovega in sum-Balabanovega indeksa, ter popravimo nekaj že objavljenih rezultatov v literaturi, ki so le delno pravilni. To nam je omogočilo dokazati domnevo M. Aouchicha, G. Caporossija in P. Hansena o primerjavi med Balabanovim in Randićevim indeksom. Prav tako smo pokazali, da za vsak k in dovolj velik n velja, da je prvih k grafov reda n z največjo vrednostjo Balabanovega indeksa, enakih drevesom. Članek zaključimo z rezultatom o stekališčih sum-Balabanovega indeksa.
Keywords:topološki indeks, Balaban indeks, sum-Balaban indeks, Randić indeks
