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…
Efficient algorithm for the vertex connectivity of trapezoid graphs
Aleksandar Ilic
The intersection graph of a collection of trapezoids with corner points lying on two parallel lines is called a trapezoid graph. These graphs and their generalizations were applied…
On the extremal properties of the average eccentricity
Aleksandar Ilic
The eccentricity of a vertex is the maximum distance from it to another vertex and the average eccentricity of a graph is the mean value of eccentricities of all vert…
On vertex covers and matching number of trapezoid graphs
Aleksandar Ilic, Andreja Ilic
The intersection graph of a collection of trapezoids with corner points lying on two parallel lines is called a trapezoid graph. Using binary indexed tree data structure, we improv…
On the Wiener index and Laplacian coefficients of graphs with given diameter or radius
Aleksandar Ilic, Andreja Ilic, Dragan Stevanovic
Let be a simple undirected -vertex graph with the characteristic polynomial of its Laplacian matrix , . It is we…
The largest Hosoya indices of unicyclic graphs
Guihai Yu, Lihua Feng, Aleksandar Ilic
The Hosoya index of a graph is defined as the total number of edge independent sets of . In this paper, we extend the research of [J. Ou, On extremal unicyclic molec…
