  • The group inverse of circulant matrices depending on four parameters 

    Carmona Mejías, Ángeles; Encinas Bachiller, Andrés Marcos; Jiménez Jiménez, María José; Mitjana Riera, Margarida (De Gruytr, 2021-10-27)
    Article
    Open Access
    Explicit expressions for the coefficients of the group inverse of a circulant matrix depending on four complex parameters are analytically derived. The computation of the entries of the group inverse are now reduced to the ...

    Article
    Restricted access - publisher's policy
    A bipartite graph G = (V, E) with V = V1 ¿ V2 is biregular if all the vertices of a stable set Vi have the same degree ri for i = 1, 2. In this paper, we give an improved new Moore bound for an infinite family of such ...

  • On d-Fibonacci digraphs 

    Dalfó Simó, Cristina; Fiol Mora, Miquel Àngel (2021-10-03)
    Article
    Open Access
    The d-Fibonacci digraphs F(d, k), introduced here, have the number of vertices following some generalized Fibonacci-like sequences. They can be defined both as digraphs on alphabets and as iterated line digraphs. Here we ...

  • Ionospheric tomographic common clock model of undifferenced uncombined GNSS measurements

  • A combinatorial expression for the group inverse of symmetric M-matrices 

    Carmona Mejías, Ángeles; Encinas Bachiller, Andrés Marcos; Mitjana Riera, Margarida (De Gruytr, 2021-04-27)
    Article
    Open Access
    By using combinatorial techniques, we obtain an extension of the matrix-tree theorem for general symmetric M-matrices with no restrictions, this means that we do not have to assume the diagonally domi nance hypothesis. We ...
