An edge centrality measure based on the Kemeny constant
D. Altafini, D. A. Bini, V. Cutini +2
A new measure of the centrality of an edge in an undirected graph is introduced. It is based on the variation of the Kemeny constant of the graph after removing the…
Numerical solution of a matrix integral equation arising in Markov Modulated Lévy processes
Dario A. Bini, Guy Latouche, Beatrice Meini
Markov-modulated Lévy processes lead to matrix integral equations of the kind where , , are given matrix coefficients, while …
Geometric means of quasi-Toeplitz matrices
Dario A. Bini, Bruno Iannazzo, Jie Meng
We study means of geometric type of quasi-Toeplitz matrices, that are semi-infinite matrices of the form , where represents a compact o…
A family of fast fixed point iterations for M/G/1-type Markov chains
Dario Andrea Bini, Guy Latouche, Beatrice Meini
We consider the problem of computing the minimal nonnegative solution of the nonlinear matrix equation where , for , are nonnega…
A computational framework for two-dimensional random walks with restarts
Dario A. Bini, Stefano Massei, Beatrice Meini +1
The treatment of two-dimensional random walks in the quarter plane leads to Markov processes which involve semi-infinite matrices having Toeplitz or block Toeplitz structure plus a…
Solving quadratic matrix equations arising in random walks in the quarter plane
Dario A. Bini, Beatrice Meini, Jie Meng
Quadratic matrix equations of the kind are encountered in the analysis of Quasi--Birth-Death stochastic processes where the solution of interest is the minim…
