The Harary index of trees
Aleksandar Ili\' c, Guihai Yu, Lihua Feng
The Harary index of a graph is recently introduced topological index, defined on the reverse distance matrix as , where is th…
On the ordering of trees by the Laplacian coefficients
Aleksandar Ili\' c
We generalize the results from [X.-D. Zhang, X.-P. Lv, Y.-H. Chen, \textit{Ordering trees by the Laplacian coefficients}, Linear Algebra Appl. (2009), doi:10.1016/j.laa.2009.04.018…
Eccentric Connectivity Index of Chemical Trees
Aleksandar Ili\' c, Ivan Gutman
The eccentric connectivity index is a distance--based molecular structure descriptor that was recently used for mathematical modeling of biological activities of diverse natu…
Distance spectra and Distance energy of Integral Circulant Graphs
Aleksandar Ili\' c
The distance energy of a graph is a recently developed energy-type invariant, defined as the sum of absolute values of the eigenvalues of the distance matrix of . There was…
