  • Stratifying systems via relative projective modules
    Marcos, ED; Mendoza, O; Saenz, C (2005)
    In this paper we point out that the "Process of standardization", given in Dlab and Ringel (1992), and also the "Comparison method" given in Platzeck and Reiten (2001) can be generalized. To do so, live introduce the concept ...
  • Stratifying systems via relative simple modules
    Marcos, ED; Mendoza, O; Saenz, C (2004)
    In this paper we continue the study of stratifying systems, which were introduced by K. Erdmann and C. Saenz in [Comm. Algebra 31 (7) (2003) 3429-3446]. We show that this new concept provides a categorical generalization ...
  • Structural and Thermodynamic Properties of DNA Uncover Different Evolutionary Histories
    Miramontes, P; Medrano, L; Cerpa, C; Cedergren, R; Ferbeyre, G; Cocho, G (1995)
    We propose an index of DNA homogeneity (IDH) based on a binary distribution model that quantifies structural and thermodynamic aggregates present in DNA primary structures. Extensive analysis of sequence databases with the ...
  • A study of the dynamics of lambda sin z
    Dominguez, P; Sienra, G (2002)
    This paper studies the dynamics of the family lambda sin z for some values of lambda. First we give a description of the Fatou set for values of lambda inside the unit disc. Then for values of lambda on the unit circle of ...
  • Sumario compendioso de las cuentas de oro y plata que en los reinos del Perú son necesarias a los mercaderes y a todo género de tratantes
    Díez-Freile, J (Las Prensas de Ciencias, 2008)
    La importancia de esta obra radica en que es este el primer libro científico publicado en el continente americano en 1556.
  • Surgery and hyperbolic univalent Baker domains
    Sienra Loera, Guillermo Javier Francisco (2006)
    We call a star with n-arms a set of n univalent Baker domains (UBDs) {U-i}(i=1)(n), such that for all i, j = 1,..., n and i not equal j, (U) over bar (i) boolean AND (U) over bar (j) =. In this paper we prove that for any ...
  • Teoremas de green, gauss y stokes para funciones continuas y discontinuas
    Monsivais, G; Neymet, S (Las Prensas de Ciencias, 2008)
    El objetivo de este libro es presentar un estudio de los tres teoremas integrales más importantes del cálculo vectorial y algunas de sus formas alternativas equivalentes, tanto para funciones continuas como discontinuas. ...
  • Teoría de conjuntos para estudiantes de ciencias
    Amor-Montaño, J A (Las Prensas de Ciencias, 2009)
    Este libro constituye una introducción a la teoría de conjuntos, dirigida fundamentalmente a estudiantes del área científica así como a los de filosofía interesados en los fundamentos de las matemáticas.
  • Teoría de la medida
    Grabinsky, G (Las Prensas de Ciencias, 2009)
    En este libro encontrará el lector material para un curso de Teoría de la medida e integraciones de Lebesgue, dirigido a estudiantes que hayan llevado un curso de análisis real. Se incluyen 150 ejercicios acompañados de ...
  • Técnica actuarial de los seguros no-vida
    Minzoni-Consorti, A (Las Prensas de Ciencias, 2004)
    Este texto viene a ser una clara guía de las reglas que deben seguirse en el ejercicio de la Técnica Actuarial de los Seguros No-vida, y viene a complementar las obras del mismo autor publicadas en esta colección: ...
  • Tilting categories with applications to stratifying systems
    Mendoza, O; Saenz, C (2006)
    In the study of standardly stratified algebras and stratifying systems. we find an object which is either a tilting module or one whose properties strongly remind us of a tilting module. This tilting module appeared already ...
  • The topology of the Banach-Mazur compactum
    Antonyan, SA (2000)
    Let J(n) be the hyperspace of all centrally symmetric compact convex bodies A subset of or equal to R-n, n greater than or equal to 2, for which the ordinary Euclidean unit ball is the ellipsoid of maximal volume contained ...
  • TRAVELING-WAVE PHENOMENA IN SOME DEGENERATE REACTION-DIFFUSION EQUATIONS
    MAINI, PK; SánchezGARDUNO, F (1995)
    In this paper we study the existence of travelling wave solutions (t.w.s.), u(x, t) = phi(x-ct) for the equation () partial derivative u/partial derivative t=partial derivative/partial derivative x[D(u)partial derivative ...
  • Travelling wave phenomena in non-linear diffusion degenerate Nagumo equations
    Maini, PK; SánchezGarduno, F (1997)
    In this paper we study the existence of one-dimensional travelling wave solutions u(x, t) = phi(x - ct) for the non-linear degenerate (at u = 0) reaction-diffusion equation u(t) = [D(u)u(x)](x) + g(u) where g is a ...
  • Travelling waves in a nonlinear degenerate diffusion model for bacterial pattern formation
    Satnoianu, RA; Maini, PK; Garduno, FS; Armitage, JP (2001)
    We study a reaction diffusion model recently proposed in [5] to describe the spatiotemporal evolution of the bacterium Bacillus subtilis on agar plates containing nutrient. An interesting mathematical feature of the model, ...
  • Triggered alternans in an ionic model of ischemic cardiac ventricular muscle
    Arce, H; Guevara, MR; López, A (2002)
    It has been known for several decades that electrical alternans occurs during myocardial ischemia in both clinical and experimental work. There are a few reports showing that this alternans can be triggered into existence ...
  • Ultrafilters, monotone functions and pseudocompactness
    Hrusak, M; Sanchis, M; Tamariz, A (2005)
    that is, {n<&omega;:V&AND;U-n&NOTEQUAL;&phi;} &ISIN
  • Umbilicity of surfaces with orthogonal asymptotic lines in R-4
    Romero-Fuster, MD; Sánchez-Bringas, F (2002)
    We study some properties of surfaces in 4-space all whose points are umbilic with respect to some normal field. In particular, we show that this condition is equivalent to the orthogonality of the (globally defined) fields ...
  • Una introducción a la geometría hiperbólica bidimensional
    Lascurain, A (Las Prensas de Ciencias, 2005)
    La geometría hiperbólica es una fascinante rama de las matemáticas donde aparecen de manera natural las teselaciones, los fractales, la teoría de la relatividad y muchos otros temas centrales de la ciencia del siglo XXI.
  • Universal proper G-spaces
    Antonyan, SA (2002)
    It is proved that: (1) every Lie group G can act properly (in sense of Palais) on each infinite-dimensional Hilbert space 12 (T) of a given weight tau such that (G, l(2) (tau)) becomes a universal G-space for all metrizable ...
