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…

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…
