      Comunicació de congrés
      Accés obert
      In this work we derive the Creen function of a generalized linear Polyomino as a suitable perturbation of the Creen function of a Hamiltonian path on it. So, our study encompasses previous work:; on polyomino-like chains.
    • Generalizing the bottleneck matrix 

      Carmona Mejías, Ángeles; Encinas Bachiller, Andrés Marcos; Mitjana Riera, Margarida; Monsó Burgués, Enrique P.J. (2019)
      Text en actes de congrés
      Accés obert
      Given the Laplacian matrix associated to a weighted graph and given x a single vertex of it, the bottleneck matrix (related to x) is the inverse matrix of the sub matrix of the Laplacian obtained by eliminating the row ...
