    This work consists of five chapters and an appendix, organized from the following shape: Chapter 1 of this paper is dedicated to the introduction and begins with a recapitulation of the theory about non-linear EDPs and the ...
  • DN-Problema de dispersión de una onda plana sobre una cuña 
    de la Paz Méndez, José Eligio (Universidad Michoacana de San Nicolás de Hidalgo, 2010-11)
    In this work we continue with the mathematical justification of the theory of dispersion dependent on time on wedges. In articles [1] - [2] this problem was analyzed for wedges that satisfy the border conditions of Dirichlet ...
  • Operador pseudodiferencial en semirrecta y problema de Riemann-Hilbert

    In the present thesis, we study an initial border problem for a equation Pseudodifferential with more general symbol K (p) = | p | Α, 12 <α <1. The basic question about the number of boundary conditions that must be fixed ...
  • Modelos cosmológicos dominados por materia con viscosidad volumétrica para explicar la expansión acelerada del Universo 
    Avelino Huerta, Arturo (Universidad Michoacana de San Nicolás de Hidalgo, 2010-11)
    In 1998, through type Ia supernova observations (SNe Ia), it was discovered that the Universe seemed to be expanding rapidly today. This attracted the attention of a great number of cosmologists, astrophysicists and ...
  • Vértices y propagadores en la electrodinámica cuántica escalar 
    Concha Sánchez, Yajaira (Universidad Michoacana de San Nicolás de Hidalgo, 2009-06)
    The Standard Model (SM) of elementary particles is the theory of electro-weak interaction (which describes weak and electromagnetic interactions). The Standard Model was proposed in 1967 by Salam, Weinberg and Glashow. ...

    The work is distributed as follows. In Chapter 1 we review some notions and results on the spaces and the theory of the convexity that they require in the present work. We also study two versions of the Farkas Lemma that ...
  • La estructura de los espaciotiempos que representan a los agujeros de gusano 
    Montelongo García, Nadiezhda (Universidad Michoacana de San Nicolás de Hidalgo, 2009-08)
    In this thesis we make a contribution to the theory of wormholes introducing a new way of building such spaces. He central ingredient of this construction is the "throat", and our idea has been discussed in [12, 13]. We ...
  • Pozos potenciales de poca profundidad para la ecuación discreta de Schrödinger 
    Rodriguez Ceballos, Joel Arturo (Universidad Michoacana de San Nicolás de Hidalgo, 2007-05)
