Complete characterization of the minimal-ABC trees
Darko Dimitrov, Zhibin Du
The problem of characterizing trees with minimal atom-bond-connectivity index (minimal-ABC trees) has a reputation as one of the most demanding recent open optimization problems in…
Estimating Some General Molecular Descriptors of Saturated Hydrocarbons
Akbar Ali, Zhibin Du, Kiran Shehzadi
Three general molecular descriptors, namely the general sum-connectivity index, general Platt index and ordinary generalized geometric-arithmetic index, are studied here. Best poss…
The Kirchhoff indices and the matching numbers of unicyclic graphs
Xuli Qi, Bo Zhou, Zhibin Du
The Kirchhoff index of a connected graph is the sum of resistance distances between all unordered pairs of vertices in the graph. It found considerable applications in a variety of…
Sum-connectivity indices of trees and unicyclic graphs of fixed maximum degree
Zhibin Du, Bo Zhou, Nenad Trinajstic
We obtain the maximum sum-connectivity indices of graphs in the set of trees and in the set of unicyclic graphs respectively with given number of vertices and maximum degree, and d…
Reverse degree distance of unicyclic graphs
Zhibin Du, Bo Zhou
The reverse degree distance is a connected graph invariant closely related to the degree distance proposed in mathematical chemistry. We determine the unicyclic graphs of given gir…
On eccentric connectivity index
Bo Zhou, Zhibin Du
The eccentric connectivity index, proposed by Sharma, Goswami and Madan, has been employed successfully for the development of numerous mathematical models for the prediction of bi…
