Boundary value problems for second order linear difference equations: application to the computation of the inverse of generalized Jacobi matrices
(Springer, 2019-07-22)
Article
Accés obertWe have named generalized Jacobi matrices to those that are practically tridiagonal, except for the two final entries and the two first entries of its first andits last row respectively. This class of matrices encompasses ... -
Effective resistances and Kirchhoff index in subdivision networks
(Taylor & Francis, 2016-11-12)
Article
Accés obertWe define a subdivision network ¿S 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 electrical conditions on the new network. In ... -
Eigenvalues with respect to a weight for general boundary value problems on networks
(Elsevier, 2021-04-01)
Article
Accés obertIn this work we analyze self-adjoint boundary value problems on networks for Schrödinger operators, in which a part of the boundary with a Neumann condition is always considered. We first characterize when the energy is ... -

Group inverse matrix of the normalized Laplacian on subdivision networks
(2020)
Article
Accés obertIn this paper we consider a subdivision of a given network and we show how the group inverse matrix of the normalized laplacian of the subdivision network is related to the group inverse matrix of the normalized laplacian ... -

On the spatial behavior in two-temperature generalized thermoelastic theories
(2017-10-01)
Article
Accés obertThis paper investigates the spatial behavior of the solutions of two generalized thermoelastic theories with two temperatures. To be more precise, we focus on the Green–Lindsay theory with two temperatures and the Lord–Shulman ... -
On the time decay in phase-lag thermoelasticity with two temperatures
(AMER INST MATHEMATICAL SCIENCES-AIMS, 2019-09-12)
Article
Accés obertThe aim of this paper is to study the time decay of the solutions for two models of the one-dimensional phase-lag thermoelasticity with two temperatures. The first one is obtained when the heat flux vector and the inductive ... -
Some non-selfadjoint problems on the circle
(1998)
Article
Accés obertThe non-selfadjoint nature of some second order differential equations with periodic boundary conditions is exhibited by describing properties of its spectrum, such as geometric and algebraic multiplicities and existence ... -
Some qualitative results for a modification of the Green–Lindsay thermoelasticity
(2018-11)
Article
Accés obertIn this short note we consider a recent modification of the Green–Lindsay thermoelastic theory proposed at Yu et al. (Meccanica 53:2543–2554, 2018). We consider a functional defined on the solutions of the problem. It ...
