PATH-ORDERED PHASE-FACTORS IN SCALAR QUANTUM ELECTRODYNAMICS
(Kyoto Univ, 1995-06-01)
Starting from linear equations for the complex scalar field, the two- and three-point Green's functions are obtained in the infrared approximation. We show that the infrared singularity factorizes in the vertex function ...
Conjuntos minimais de sistemas lineares por partes
(Universidade Estadual Paulista (Unesp), 2014-05-09)
The main goal of this thesis is to find periodic solutions of non–smooth systems. Our contribution in this thesis is related to the study of piecewise linear vector fields, singularly perturbed non–smooth systems and cubic ...
Retroalimentación de estado de sistemas singularmente perturbados en un enfoque de Bond Graph
(Universidad Michoacana de San Nicolás de Hidalgo, 2014-08)
This thesis proposes the construction of modeling singularly perturbed systems with state feedback on Bond Graph. Taking advantage of the property that have singularly perturbed systems be separable into two subsystems in ...

Model reduction of a flexible-joint robot: a port-Hamiltonian approach
(IFAC-PapersOnLine, 2016)
In this paper we explore the methodology of model order reduction based on singular perturbations for a flexible-joint robot within the port-Hamiltonian framework. We show that a flexible-joint robot has a port-Hamiltonian ...
Agujeros negros tridimensionales acoplados a campos conformes
(Universidad de Chile, 1996)
A three dimensional black hole solution of Einstein equations with negative
cosmological constant coupled to a conformal scalar field is given. The solution is
static, circularly symmetric, asymptotically anti-de sitter ...
Renormalization in non-relativistic quantum mechanics
(Iop Publishing Ltd, 1997-09-21)
The importance and usefulness of renormalization are emphasized in non-relativistic quantum mechanics. The momentum space treatment of both two-body bound state and scattering problems involving some potentials singular ...

Magnetised accretion discs in Kerr spacetimes
(EDP Sciences, 2015-02)
Context. Observational data from X-ray binary systems provide strong evidence of astronomical objects that are too massive and compact to be explained as neutron or hybrid stars. When these systems are in the thermal ...
