Perturbing networks
Mitjana Riera, Margarida; Carmona Mejías, Ángeles; Encinas Bachiller, Andrés Marcos (2012)
Comunicació de congrés
Accés obertSemi-definite positive Schrödinger operators on finite connected networks are particular examples of a general class of self-adjoint operators called elliptic operators. Any elliptic operator defines an automorphism on the ... -
Potential Theory for boundary value problems on finite networks
Bendito Pérez, Enrique; Carmona Mejías, Ángeles; Encinas Bachiller, Andrés Marcos; Gesto Beiroa, José Manuel (2006-07)
Article
Accés obertWe aim here at analyzing self-adjoint boundary value problems on finite networks associated with positive semi-definite Schrödinger operators. In addition, we study the existence and uniqueness of solutions and its ... -

Problemas de contorno discretos
Encinas Bachiller, Andrés Marcos (Universitat Politècnica de Catalunya, 2001-10-01)
Tesi
Accés obertEn este trabajo se ha desarrollado un cálculo vectorial sobre estructuras discretas, análogo al de los modelos continuos. Para ello se ha considerado como espacio subyacente un multigrafo finito o variedad discreta y se ... -
Random walks associated with symmetric M-matrices
Carmona Mejías, Ángeles; Encinas Bachiller, Andrés Marcos; Jiménez Jiménez, María José; Martin Llopis, Álvar (Elsevier, 2023-10)
Article
Accés obertIn this paper we generalize the transition probability matrix for a random walk on a finite network by defining the transition probabilities througha symmetric M-matrix. Usually, the walker jumps from a vertex to a ... -
Recovering piecewise constant conductances on networks with boundary
Carmona Mejías, Ángeles; Encinas Bachiller, Andrés Marcos; Jiménez Jiménez, María José; Samperio Valdivieso, Álvaro (2023)
Text en actes de congrés
Accés obertThe problem of recovering the conductances of a well-connected spider net-work with boundary from its Dirichlet-to-Robin map is ill-posed for large networks, so despite there is an exact algorithm to solve it [1], the ... -
Recovering the conductances on grids
Arauz Lombardía, Cristina; Carmona Mejías, Ángeles; Encinas Bachiller, Andrés Marcos (2014)
Article
Accés restringit per política de l'editorialIn 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. -
Recovering the conductances on grids: A theoretical justification
Arauz Lombardía, Cristina; Carmona Mejías, Ángeles; Encinas Bachiller, Andrés Marcos; Mitjana Riera, Margarida (2016)
Article
Accés obertIn 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, ... -
Redes estrella con la M-propiedad
Encinas Bachiller, Andrés Marcos (Editorial Universidad de Almería, 2015)
Text en actes de congrés
Accés obertEn este trabajo hacemos una aportación al problema inverso de M –matrices irreducibles, simétricas y singulares, que consiste en determinar c uándo su inversa de grupo es también una M –matriz. Mostramos primero que las ... -
Regular boundary value problems on a path throughout Chebyshev Polynomials
Bendito Pérez, Enrique; Carmona Mejías, Ángeles; Encinas Bachiller, Andrés Marcos; Gesto Beiroa, José Manuel (2006-08)
Article
Accés obertIn this work we study the different types of regular boundary value problems on a path associated with the Schrödinger operator. In particular, we obtain the Green function for each problem and we emphasize the case of ... -
Resistance distances in extended or contracted networks
Carmona Mejías, Ángeles; Encinas Bachiller, Andrés Marcos; Mitjana Riera, Margarida (Elsevier, 2019-09-01)
Article
Accés obertIn this paper we introduce new effective resistances on a given network, associated with a positive value and two weights on the vertex set and investigate under which conditions they determine a distance. We prove that ... -
Resistance distances on networks
Carmona Mejías, Ángeles; Encinas Bachiller, Andrés Marcos; Mitjana Riera, Margarida (2017)
Article
Accés obertThis paper aims to study a family of distances in networks associated witheffective resistances. Speci cally, we consider the e ective resistance distance with respect to a positive parameter and a weight on the vertex ... -

Text en actes de congrés
Accés obertFor spreading and diffusion processes, Random Walks (RW) represents a mathe- matical model and can be used to extract information about important issues in networks. In the study of networks, one often seeks to rank nodes, ... -
Second order linear difference equations
Encinas Bachiller, Andrés Marcos; Jiménez Jiménez, María José (2017-12-04)
Article
Accés obertWe provide the explicit solution of a general second order linear difference equation via the computation of its associated Green function. This Green function is completely characterized and we obtain a closed expression ... -
