Kemeny's constant via matrix compression and eigenvalue interlacing
A. Abiad, Á. Carmona, A. M. Encinas +3
Kemeny's constant quantifies the expected time for a random walk to reach a randomly chosen vertex, capturing global properties of a Markov chain. We develop a matrix-analytic fram…
The -matrix group inverse problem for recoverable complete networks
Angeles Carmona, Andrés M. Encinas, Sweta Patra +1
This study investigates the conditions under which the group inverse of a singular, irreducible, symmetric -matrix retains the -matrix property. By concentrating on a structu…
Stable recovery of piecewise constant conductance on spider networks
Ángeles Carmona, Andrés M. Encinas, María José Jiménez +1
We address the discrete inverse conductance problem for well-connected spider networks; that is, to recover the conductance function on a well-connected spider network from the Dir…
The -matrix group inverse problem for distance-biregular graphs
Aida Abiad, Ángeles Carmona, Andrés M. Encinas +1
In this paper we provide the group inverse of the combinatorial Laplacian matrix of distance-biregular graphs using the so-called equilibrium measures for sets obtained by deleting…
Effective resistances and Kirchhoff Index in subdivision networks
Ángeles Carmona, Margarida Mitjana, Enric Monsó
We define a subdivision network of a given network by inserting a new vertex in every edge, so that each edge is replaced by two new edges with conductances that fulfill…
Green Operators of Networks with a new vertex
A. Carmona, A. M. Encinas, S. Gago +1
Any elliptic operator defines an automorphism on the orthogonal subspace to the eigenfunctions associated with the lowest eigenvalue, whose inverse is the orthogonal Green operator…
The inverse matrix of some circulant matrices
A. Carmona, A. M. Encinas, S. Gago +2
We present here necessary and sufficient conditions for the invertibility of circulant and symmetric matrices that depend on three parameters and moreover, we explicitly compute th…
