Boundary value problems for Schrödinger operators on a path
(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 ... -

(Springer, 2013)
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 ... -
Bounds on the first non-null eigenvalue for self-adjoint boundary value problems on networks
(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 ... -
Condiciones de contorno en modelos de gradiente con desplazamientos suavizados
(2012)
Article
Accés obertLos modelos de gradiente basados en desplazamientos suavizados son una alternativa a los modelos est´andares para simular num´ericamente el proceso de fallo de materiales. En esta formulaci´on alternativa coexisten los ... -
Frozen Jacobian multistep iterative method for solving nonlinear IVPs and BVPs
(2017-01-01)
Article
Accés obertIn this paper, we present and illustrate a frozen Jacobian multistep iterative method to solve systems of nonlinear equations associated with initial value problems (IVPs) and boundary value problems (BVPs). We have used ... -
Generalized equipartition theorem and confining walls
(2015-06)
Article
Accés obertIt is shown that the generalized equipartition theorem as applied to the momentum may fail, even though the usual conditions of validity are met. This failure is linked to the nature of the confining walls, with ideal walls ... -
Nonreal eigenvalues for second order differential operators on networks with circuits
(2001)
Article

Overdetermined partial boundary value problems on finite networks
(2015-03-01)
Article
Accés obertIn 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, ... -
Overdetermined partial resolvent kernels for finite networks
(2016-03-01)
Article
Accés obertIn [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 ... -
Potential Theory for boundary value problems on finite networks
(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 ... -
Regular boundary value problems on a path throughout Chebyshev Polynomials
(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 ... -
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 ... -
Vortex rings impinging on permeable boundaries
(2015-01)
Article
Accés obertExperiments with vortex rings impinging permeable and solid boundaries are presented in order to investigate the influence of permeability. Utilizing Particle Image Velocimetry, we compared the behaviour of a vortex ring ...
