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…
Laplacian Estrada index of trees
Aleksandar Ilic, Bo Zhou
Let be a simple graph with vertices and let be the eigenvalues of its Laplacian matrix. The Laplacian…
On sum of powers of Laplacian eigenvalues and Laplacian Estrada index of graphs
Bo Zhou
Let be a simple graph and a real number. The quantity defined as the sum of the -th power of the non-zero Laplacian eigenvalues of generalizes several conce…
On Distance Spectral Radius and Distance Energy of Graphs
Bo Zhou, Aleksandar Ilic
For a connected graph, the distance spectral radius is the largest eigenvalue of its distance matrix, and the distance energy is defined as the sum of the absolute values of the ei…
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…
