  • (1)(2)-Homogeneous continua with cut points
    Nadler, SB; Pellicer-Covarrubias, P; Puga, I (2007)
    A space is said to be _21-homogeneous provided that there are exactly two orbits for the action of the group of homeomorphisms of the space onto itself. It is shown that if X is a 1/2-homogeneous continuum with at least ...
  • Adjunction spaces and unions of G-ANE's
    Elfving, E; Mata-Romero, A; Antonyan, SA (2002)
    Let G be a locally compact Hausdorff group. We study adjunction spaces and unions of equivariant absolute neighborhood extensors (G-ANE's) in the category of all proper G-spaces that axe metrizable by G-invariant metrics. ...
  • Alberto barajas. Su oratoria, sus matemáticas y sus enseñanzas
    Neumann-Lara, V (Las Prensas de Ciencias, 2009)
    Este volumen constituye un homenaje al maestro Barajas en el que converge el esfuerzo de muchos universitarios que tuvieron el privilegio de ser sus alumnos y, en algunos casos, sus amigos. El lector encontrará aquí ...
  • Algebra lineal
    Rincón-Mejía, H A (Las Prensas de Ciencias, 2006)
    Operaciones asociativas; espacios vectoriales; transformaciones lineales; determinantes; polinomios y formas canónicas son algunos de los temas tratados en este libro.
  • Algebra superior
    Bravo, Alejandro; Rincón, H; Rincón, C (Las Prensas de Ciencias, 2006)
    Entre los temas incluidos en este volumen se encuentran una introducción a la lógica matemática y a la teoría de conjuntos y, por supuesto, incluye todos los temas que normalmente se imparten en un curso de álgebra superior.
  • Algebras whose tits form weakly controls the module category
    Coelho, F; delaPena, JA; Tomé, BM (1997)
  • THE ALPHA-BOUNDIFICATION OF ALPHA
    GarcíaFERREIRA, S; Tamariz, A (1993)
    A space X is < alpha-bounded if for all A subset-or-equal-to X with ]A] < alpha cl(x) A is compact. Let B (alpha) be the smallest < alpha-bounded subspace of beta (alpha) containing alpha. It is shown that the following ...
  • Alternans and higher-order rhythms in an ionic model of a sheet of ischemic ventricular muscle
    Arce, H; Xu, AX; Guevara, MR; González, H (2000)
    Life-threatening arrhythmias such as ventricular tachycardia and fibrillation often occur during acute myocardial ischemia. During the first few minutes following coronary occlusion, there is a gradual rise in the extracellular ...
  • Alternating chaotic and periodic dynamics in Chern-Simons-Higgs theory with scalar magnetic interaction
    Escalona, J; Antillon, A; Jiang, Y; Parmananda, P; Villavicencio, M (2000)
    The dynamical behavior of a Chern-Simons-Higgs system is studied for the spatially homogeneous case. The model, described by interacting gauge and scalar fields includes two parity and time violating terms: the Chern-Simons ...
  • Analysis of a Dengue disease transmission model
    Esteva, L; Vargas, C (1998)
    A model for the transmission of dengue fever in a constant human population and variable vector population is discussed. A complete global analysis is given, which uses the results of the theory of competitive systems and ...
  • ANALYSIS OF AN AUTONOMOUS PHASE MODEL FOR NEURONAL PARABOLIC BURSTING
    RINZEL, J; CARRILLO, H; Baer, SM (1995)
    An understanding of the nonlinear dynamics of bursting is fundamental in unraveling structure-function relations in nerve and secretory tissue. Bursting is characterized by alternations between phases of rapid spiking and ...
  • Applications of stratifying systems to the finitistic dimension
    Marcosa, ED; Mendoza, O; Saenz, C (2006)
    Given an Ext-injective stratifying system of A-modules (theta, (Y) over bar, less than or similar to) satisfying that the projective dimension of Y is finite, we prove that the finitistic dimension of the algebra A is equal ...
  • Approximations to the configurational energy of dipolar particles on a 2D lattice
    Arce, H; Miramontes, P; López, A; Sánchez, V (1997)
    Current research on critical phenomena and minimum energy configurations of dipolar particles on a 2D lattice, usually approximates the infinite interaction range through a cutoff to carry out numerical simulations. In ...
  • ASSESSING THE SUITABILITY OF STERILE INSECT TECHNIQUE APPLIED TO AEDES AEGYPTI
    Ferreira, CP; Yang, HM; Esteva, L (2008)
    The efficacy of biological control of Aedes aegypti mosquitoes using Sterile Insect Technique (SIT) is analyzed. This approach has shown to be very efficient on agricultural plagues and has become an alternative control ...
  • Asymptotic measures of random logistic maps
    Ble, G; Castellanos, V; Falconi, M (2007)
    In this paper, we consider a system whose state x changes to F-sigma(x) if a perturbation occurs at the time t, for t > 0
  • Asymptotic properties of two interacting maps
    Ble, G; Castellanos, V; Falconi, MJ (2003)
    In this paper we consider a system whose state x changes to sigma(x) if a perturbation occurs at the time t, for t > 0, t is not an element of N. Moreover, the state x changes to the new state eta(x) at time t, for t is ...
  • Asymptotics for supersonic soliton propagation in the Toda lattice equation
    Unknown author (2008)
    We study the problem of the adjustment of an initial condition to an exact supersonic soliton solution of the Toda latice equation. Also, we study the problem of soliton propagation in the Toda lattice with slowly varying ...

  • The Banach-Mazur compactum BM(2) is homeomorphic to the orbit space (exp S-1)/O(2)
    Antonyan, SA (2007)
    We prove a general theorem about the orbit spaces of compact Lie group actions which are Hilbert cube manifolds. This result is further applied to prove that the Banach-Mazur compactum BM(2) is homeomorphic to the orbit ...
