A note on extremal Sombor indices of trees with a given degree sequence
Ivan Damnjanović, Marko Milošević, Dragan Stevanović
We note here that the problem of determining extremal values of Sombor index for trees with a given degree sequence fits within the framework of results by Hua Wang from [Cent. Eur…
Greedy trees have minimum Sombor indices
Ivan Damnjanović, Dragan Stevanović
Recently, Gutman [MATCH Commun. Math. Comput. Chem. 86 (2021) 11-16] defined a new graph invariant which is named the Sombor index of a graph and is computed v…
Spectral properties of balanced trees and dendrimers
Ivan Damnjanović, Slobodan Filipovski, Dragan Stevanović
We investigate the spectral properties of balanced trees and dendrimers, with a view toward unifying and improving the existing results. Here we find a semi-factorized formula for…
