Bisymmetric non-negative Jacobi matrix realizations
Encinas Bachiller, Andrés Marcos; Jiménez Jiménez, María José; Marijuan López, Carlos; Mitjana Riera, Margarida; Pisonero Pérez, Miriam (Taylor & Francis Group, 2023-12-21)
Article
Accés restringit per política de l'editorialWithin the symmetric inverse eigenvalue problem, the case of bisymmetric Jacobi matrices occupies a central place, since for any strictly monotone list of n real numbers there exists a unique bisymmetric Jacobi matrix ... -
Boundary value problems for Schrödinger operators on a path
Carmona Mejías, Ángeles; Encinas Bachiller, Andrés Marcos; Gago Álvarez, Silvia (2012-05-25)
Report de recerca
Accés obertIn this work, we concentrate on determining explicit expressions, via suitable orthogonal polynomials on the line, for the Green function associated with any regular boundary value problem on a weighted path, whose weights ... -

Capítol de llibre
Accés restringit per política de l'editorialIn this work, we concentrate on determining explicit expressions, via suitable orthogonal polynomials on the line, for the Green function associated with any regular boundary value problem on a weighted path, whose weights ... -
Boundary value problems for second order linear difference equations: application to the computation of the inverse of generalized Jacobi matrices
Encinas Bachiller, Andrés Marcos; Jiménez Jiménez, María José (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 ... -
Bounded solutions of second order lineal difference equations with periodic coefficients
Encinas Bachiller, Andrés Marcos; Jiménez Jiménez, María José (2016)

Bounded solutions of self-adjoint second order linear difference equations with periodic coefficients
Encinas Bachiller, Andrés Marcos; Jiménez Jiménez, María José (2018-02-25)
Article
Accés obertIn this work we obtain easy characterizations for the boundedness of the solutions of the discrete, self–adjoint, second order and linear unidimensional equations with periodic coefficients, including the analysis of the ... -
Bounds on the first non-null eigenvalue for self-adjoint boundary value problems on networks
Bendito Pérez, Enrique; Carmona Mejías, Ángeles; Encinas Bachiller, Andrés Marcos; Gesto Beiroa, José Manuel (2006-09)
Article
Accés obertWe aim here at obtaining bounds on the first non-null eigenvalue for self-adjoint boundary value problems on a weighted network by means of equilibrium measures, that includes the study of Dirichlet, Neumann and Mixed ... -

Cálculo de la inversa de una matriz de Jacobi
Encinas Bachiller, Andrés Marcos; Jiménez Jiménez, María José (Universidad de Cádiz, 2017)
Text en actes de congrés
Accés restringit per política de l'editorialEn este trabajo aportamos las condiciones necesarias y suficientes para la invertibilidad de las matrices de Jacobi y calculamos explícitamente su inversa. Las técnicas que utilizamos están relacionadas con la soluciones ... -
Characterization of symmetric M-matrices as resistive inverses
Bendito Pérez, Enrique; Carmona Mejías, Ángeles; Encinas Bachiller, Andrés Marcos; Gesto Beiroa, José Manuel (2007-01-25)
Article
Accés obertWe aim here at characterizing those nonnegative matrices whose inverse is an irreducible Stieltjes matrix. Specifically, we prove that any irreducible Stieltjes matrix is a resistive inverse. To do that we consider the ... -
Combinatorial recurrences and linear difference equations
Jiménez Jiménez, María José; Encinas Bachiller, Andrés Marcos (2016)
Text en actes de congrés
Accés restringit per política de l'editorialIn this work we introduce the triangular arrays of depth greater than 1 given by linear recurrences, that generalize some well-known recurrences that appear in enumerative combinatorics. In particular, we focussed on ... -

Computational cost of the Fekete problem
Bendito Pérez, Enrique; Carmona Mejías, Ángeles; Encinas Bachiller, Andrés Marcos; Gesto Beiroa, José Manuel (2007-10-11)
Article
Accés obertWe present here strong numerical and statistical evidence of the fact that the Smale's 7th problem can be answered affirmatively. In particular, we show that a local minimum for the logarithmic potential energy in the ... -
