Discrete Serrin's problem
(Elsevier, 2015-03-01)
Article.
Accés obert
Article.
Accés obert
We consider here the discrete analogue of Serrin's problem: if the equilibrium measure of a network with boundary satisfies that its normal derivative is constant, what can be said about the structure of the network and ...
Discrete inverse problem on grids

In this work, we present an algorithm to the recovery of the conductance of a n –dimensional grid. The algorithm is based in the solution of some overdetermined partial boundary value problems defined on the grid; that is, ...
Overdetermined partial resolvent kernels for finite networks
(2016-03-01)
Article.
Accés obert
Article.
Accés obert
In [2], a study of the existence and uniqueness of solution of partial overdetermined boundary value problems for finite networks was performed. These problems involve Schrodinger operators and the novel feature is that ...
Recovering the conductances on grids: A theoretical justification
(2016)
Article.
Accés obert
Article.
Accés obert
In this work, we present an overview of the work developed by the
authors in the context of inverse problems on nite networks. This study performs
an extension of the pioneer studies by E.B. Curtis and J.A. Morrow, ...
Dirichlet-to-Robin matrix on networks
(2014)
Article.
Accés obert
Article.
Accés obert
In this work, we de ne the Dirichlet{to{Robin matrix associated with a Schr odinger
type matrix on general networks, and we prove that it satis es the alternating
property which is essential to characterize those matrices ...
Overdetermined partial boundary value problems on finite networks
(2015-03-01)
Article.
Accés obert
Article.
Accés obert
In this study, we define a class of non-self-adjoint boundary value problems on finite networks associated with Schrodinger operators. The novel feature of this study is that no data are prescribed on part of the boundary, ...
Funciones de green en redes producto

En esta comunicación presentaremos la versión discreta del método de separación
de variables para determinar la función de Green de redes producto en términos
de la función de Green de uno de las redes factores y los ...
Dirichlet-to-Robin maps on finite networks
(2015-04-01)
Article.
Accés obert
Article.
Accés obert
Our aim is to characterize those matrices that are the response matrix of a semi positive definite Schrodinger operator on a circular planar network. Our findings generalize the known results and allow us to consider both ...

In this work, we present an algorithm to the recovery of the conductance of a 2–
dimensional grid. The algorithm is based in the solution of some overdetermined
partial boundary value problems defined on the grid.
