    • 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.
    • 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 ...
    • 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.
    • 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 ...
    • 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 ...
