  • Algoritmos de punto fijo usando subdivisiones simpliciales 

    Azofeifa Z., Carlos E. (2009-02-18)
    In this paper we study an algorithm for approximating fixed points using simplicial subdivisions of the simplex. Furthermore, it is compared with algorithms of primitive sets.
  • La Ecuación de Hill con Potencial Irregular 

    Cambronero, Santiago (2012-03-29)
    We consider the Hill equation whose potential is the formal derivative of a Hölder – continuous function of parameter \theta \in (0,1), and show that solutions of the discrete version converge to solutions of the original ...
  • Productos de Kronecker 

    Poltronieri Vargas, Jorge (2009-02-18)
    We obtain the formulae of covariances between random, introducing the Kronecker’s products: asymmetrical and antisymmetrical.
  • El incremento multivariado 

    Alarcón Athens, Winston (2012-03-29)
    We develop and study a generalization to multivariate functions of the notion of increment, by mean of we can reproduce in several variables, many importants theorems of the Calculus in one variable. In particular, it is ...
  • The multiplicative products between the Distribution (P ± i0)^{\lambda} and the Operators L^r{\delta} and K^r{\delta} 

    Aguirre T., Manuel A. (2012-03-29)
    In this note we give a sense to some multiplicative products of distributions:i) (P ± i0)^{\lambda} . L^r {\delta}ii) (P± i0) ^{\lambda} . K^r{\delta }where (P ± i0)^{\lambda} is the distribution defined by the formula ...
  • Submartingalas finitas, teoremas de convergencia y métodos no standard 

    Lobo Segura, Jaime (2012-03-29)
    Se examinan dos teoremas clásicos de convergencia de submartingalas en tiempo discreto, los de convergencia casi segura y en L^1, usando los métodos del análisis no standard. Se realiza para ello un estudio previo sobre ...
