Group Inverse of the Laplacian of Connections of Networks
S. Gago
In previous works the group inverse of a network obtained by some perturbations, as the deletion of a vertex, the addition of a new vertex, contraction of an edge, etc. is obtained…
The Group Inverse of extended Symmetric and Periodic Jacobi Matrices
S. Gago
In this work, we explicitly compute the group inverse of symmetric and periodic Jacobi matrices.
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…
A star based model for the eigenvalue power law of Internet graphs
Francesc Comellas, Silvia Gago
Using a simple deterministic model for the Internet graph we show that the eigenvalue power law distribution for its adjacency matrix is a direct consequence of the degree distribu…
