2-Dimensional invariant tori for the spatial isosceles 3-body problem
(2000)We consider the circular Sitnikov problem as a special case of the restricted spatial isosceles 3-body problem. In appropriate coordinates we show the existence of 2-dimensional invariant tori that are ... -
A(-infinity)-interpolation in the ball
(1998)We give a necessary and sufficient condition for a sequence [ak}k in the unit ball of C° to be interpolating for the class A~°° of holomorphic functions with polynomial growth. The condition, which ... -
Anàlisi de la interdisciplinarietat d’un projecte i la seva relació amb les matemàtiques
(2016-05-13)El Treball Final de Grau que es presenta a continuació és un estudi de cas sobre un projecte que es desenvolupa a l’Escola el Roure Gros amb infants de cicle mitjà, en la qual els nens i les nenes aprenen ... -
Bifurcation of relative equilibria of the (1+3)-body problem
(2015)We study the relative equilibria of the limit case of the pla- nar Newtonian 4{body problem when three masses tend to zero, the so-called (1 + 3){body problem. Depending on the values of the in- ... -
Central configurations of nested regular polyhedra for the spatial 2n–body problem
(2008)We consider 2n masses located at the vertices of two nested regular polyhedra with the same number of vertices. Assuming that the masses in each polyhedron are equal, we prove that for each ratio of ... -
Central configurations of nested rotated regular tetrahedra
(2009)In this paper we prove that there are only two different classes of central configura- tions with convenient masses located at the vertices of two nested regular tetrahedra: either when one of the ... -
Central configurations of the 4-body problem with masses m1 ¼ m2 > m3 ¼ m4 ¼ m > 0 and m small
(2014)In this paper we give a complete description of the families of central configurations of the planar 4-body problem with two pairs of equals masses and two equal masses sufficiently small. In particular, ... -
Central configurations of three nested regular polyhedra for the spatial 3n–body problem
(2009)Three regular polyhedra are called nested if they have the same number of vertices n, the same center and the positions of the vertices of the inner polyhedron ri, the ones of the medium polyhedron ... -
Double-Antiprism Central Configurations of the 3n-Body Problem
(2013)Abstract In this paper we study numerically a new type of central configurations of the 3n-body problem with equal masses which consist of three n-gons contained in three planes z = 0 and z = ±β = ... -
Equilibrium points and central configurations for the Lennard-Jones 2-and 3-body problems
(2004)Abstract. In this paper we study the relative equilibria and their stability for a system of three point particles moving under the action of a Lennard{Jones potential. A central con guration is a ... -
Estudi de l'ensenyament-aprenentatge de la multiplicació de fraccions
(2014-05-16)Aquest treball és una investigació de com cal ensenyar la multiplicació de fraccions a l’Educació Primària. S’han recollit les dades a través d’entrevistes per conèixer com 6 mestres ensenyaven aquest ... -
Families of periodic orbits for the spatial isosceles 3-body problem
(2004)We study the families of periodic orbits of the spatial isosceles 3-body problem (for small enough values of the mass lying on the symmetry axis) coming via the analytic continuation method from ... -
Games for dyscalculic children
(2015-09)One of the most popular school failures is the mathematical difficulty. Dyscalculia is a specific learning disability in mathematics, neurobiological basis that is characterized by a difficulty in ... -
Generation of symmetric periodic orbits by a heteroclinic loop formed by two singular points and their invariant manifolds of dimension 1 and 2 in R3
(2007)In this paper we will find a continuous of periodic orbits passing near infinity for a class of polynomial vector fields in R3. We consider polynomial vector fields that are invariant under a symmetry ... -

Infinitely many periodic orbits for the rhomboidal five-body problem
(2006)We prove the existence of infinitely many symmetric periodic orbits for a regularized rhomboidal five-body problem with four small masses placed at the vertices of a rhombus centered in the fifth mass. ... -
L’Escola El Colomer de Taradell (1942-‐1961): una aproximació a l'ensenyament de les Matemàtiques
(2017-03)L’Escola El Colomer va ser una escola singular en la seva època. En un dels pitjors moments de la història de l’educació del nostre país, on es feia distinció de sexes, ... -
