Convergence in nonlinear systems with a forcing term
(2009-02-18)The problem of convergence, as t ® +¥ , of solutions of the system (1) is considered. It is assumed that the functions a , f and g are of class C1 for all values of their arguments, furtermore g' (x) > 0 , f ' (x) ³ r > ... -
Coproductos fibrados de morfismos K-finitos
(2009-02-18)In this paper we study conditions under which the push-out of morphisms K-finite are K-finite, and some related problems. -
Interpretación geométrica de algunas variedades de Schubert
(2012-03-29)In this article we give some geometrical interpretations of the Schubert-varieties of the Grassmannians G(2,4),G(3,5) and G(2, 5), and some of their applications to enumerative geometry. -
Partición óptima: el algoritmo de Fisher
(2012-03-29)El algoritmo de Fisher es un algoritmo que calcula exactamente una partición óptima en k clases de un conjunto W de n individuos a los que se les ha medido una variable real v. Tal clasificación que se obtiene, aunque no ... -
Recursive formulas for partition functions
(2012-03-29)A family of functions, which share many properties with the classical partition function p(n), is studied. It is explained why these functions may be called “partition functions” and, in particular, some recursive formulas ... -
Triángulos casi congruentes
(2012-03-29)En este artículo se estudian los triángulos casi congruentes, que consisten en las parejas de triángulos que tienen exactamente 5 de sus 6 elementos congruentes. Se caracterizan todas las soluciones enteras a este problema. ...
