  • Aplicación de la técnica no estándar a una compactación de los naturales 
    Lucas Martínez, Juan Salvador (Universidad Michoacana de San Nicolás de Hidalgo, 2011-04)
    We will begin the development of this work by recalling some useful concepts that we will use throughout the material. In this chapter we will also state, although without proof, some important results. For now we will ...
  • Diseño e implementación de un convertidor trifásico en base a tiristores utilizando un DSP 
    Tapia Tinoco, Guillermo (Universidad Michoacana de San Nicolás de Hidalgo, 2008-12)
    In this research work, the design and construction of a prototype of a thyristor controlled converter are presented, which is suitable for industrial applications. The power converter, based on a six pulse three-phase ...
  • Espacios topológicos ordenados 
    Gaspar Arreola, Miguel Ángel (Universidad Michoacana de San Nicolás de Hidalgo, 2009-11)
    Topology is the mathematical discipline that studies the properties of sets in general when they are given an idea of ??closeness between the elements of the set (in this sense they are called topological spaces). In our ...
  • Esquemas de protección adaptables a los cambios de la topología de la red eléctrica 
    Nieto Jiménez, Jaime (Universidad Michoacana de San Nicolás de Hidalgo, 2007-06)
    The need for greater reliability and safety of electrical systems has led to increased use of microprocessor based relay that allows rapid and early detection of faults in it. Adaptive protection is seen as the optimal ...
  • Introducción al problema del S- y L-espacio 
    Balderas Cristóbal, Emmanuel Alejandro (Universidad Michoacana de San Nicolás de Hidalgo, 2019-06)
    In this paper, the reader is introduced to the S-space and L-space problem, which had its origins in the 1920s and was solved in 2006. In Chapter 1, some definitions and important theory results are introduced. of sets, ...
  • Invariantes cardinales de los espacios métricos monótonos 
    Martínez Celis Rodríguez, Arturo Antonio (Universidad Michoacana de San Nicolás de Hidalgo. Universidad Nacional Autónoma de México, 2011-09)
    The first chapter is titled Monotonic Metric Spaces. In this first chapter will be studied some basic properties of monotonous metric spaces and some examples will be given. If you will see some topological properties that ...
  • Números de Ramsey de ultrafiltros asociados a espacios topológicos de Ramsey 
    Navarro Flores, Sonia (Universidad Michoacana de San Nicolás de Hidalgo. Universidad Nacional Autónoma de México, 2016-01)
    Ramsey spaces theory is an area of Ramsey theory that concerns with coloring infinite sequences of objects. Transferring basic pigeon whole principles to their higher dimensional versions to increase their applicability ...
  • Productos caja y la clase de espacios discretamente generados 
    Barriga Acosta, Hector Alonzo (Universidad Michoacana de San Nicolás de Hidalgo. Universidad Nacional Autónoma de México, 2016-01)
    Theory of discretely generated spaces was introduced by A. Dow, M. Tkachenko, V. Tkachuk and R. Wilson in 2002. A discretely generated space means that the closure of each of its subsets can be obtained by the union of the ...
  • Pruebas de consistencia y espacios selectivamente separables 
    Martínez Ortiz, Luis Fernando (Universidad Michoacana de San Nicolás de Hidalgo, 2014-01)
    The thesis consists of two parts: first focuses on the basics of forcing, technique used to make consistency proofs, giving the classical theorems on the subject and then make an overview of the technique of forcing. In ...
  • Selecciones continuas, números primos y una propiedad tipo cubierta 
    Cruz Chapital, Jorge Antonio (Universidad Michoacana de San Nicolás de Hidalgo. Universidad Nacional Autónoma de México, 2020-09)
    Let (X, τ ) be a Hausdorff space and n ϵ ω. We prove that if X admits a continuous selection over Fn(X) (nonempty subsets of X of cardinality at most n), then for every n ≤ m ≤ 2n such that m is not a prime number, X admits ...
  • Sobre filtros débiles y cofinalidad de ultraproductos 
    Rivas González, Norberto Javier (Universidad Michoacana de San Nicolás de Hidalgo. Universidad Nacional Autónoma de México, 2019-02)
    This work aims to compile several results about feeble filters (or, equivalently, meager filters) and cofinality of ultrapowers, most of them taken from [4] and [7], and some proves was improved to be appropriate for the ...
  • Stochastic topology in the curve complex of a surface 
    Chávez Cáliz, Ricardo Esteban (Universidad Michoacana de San Nicolás de Hidalgo. Universidad Nacional Autónoma de México, 2020-10)
    We propose the study of rigid expansions in graphs in a stochastic context using the Radó graph and the Erdos-Rényi model. We review the motivation to study this phenomenon as a concept originally conceived in the curve ...
  • Sucesiones convergentes en grupos topológicos 
    Trejo Espinosa, Osar (Universidad Michoacana de San Nicolás de Hidalgo. Universidad Nacional Autónoma de México, 2015-07)
    In this paper we study the following question: Given a sequence (an) n2N in a topological abelian group, is there any topology _ such that (an) n2N converges to the neutral element of (G; _)? For the group of integer ...
  • Topología del espacio de subgrupos cerrados de R2 
    Villicaña Molina, Yesenia (Universidad Michoacana de San Nicolás de Hidalgo, 2013-07)
    Working with subsets of R2 did not seem as interesting as was to study the topology of some families of them. This thesis presents a study of the topology of the space of closed subgroups of R2 additives is presented. We ...
  • Topologías sobre conjuntos numerables 
    Bautista Báez, Fabiola (Universidad Michoacana de San Nicolás de Hidalgo, 2013-06)
    The present work is based on the article Analytic topologies over countable sets [6], Written by Stevo Todorcevi c and Carlos Uzcátegui, throughout this work are analyzed The first sections of the article and further explain ...
  • Torsión de Whitehead 
    Chávez Cáliz, Ricardo Esteban (Universidad Michoacana de San Nicolás de Hidalgo, 2016-05)
    Homotopy as a tool which generates topological invariants, it begins defining an equivalence relationship over functions which extends to spaces. So it allows us to define an equivalence relationship weaker than homeomorphism. ...
  • Los Ψ- Espacios 
    Arciga Alejandre, Mario (Universidad Michoacana de San Nicolás de Hidalgo, 2005-06)
    The present work aims to show the versatility that ψ-spaces have, mainly, in topics of the general topology. There is practically no compendium of elemental results, more or less ordered, about almost alien families and ...
