Integral y primitivas de Riemann
(1991)
Hacemos un breve estudio de una generalización de la noción de primitiva, que se corresponde exactamente con la integral de Riemann. Obtenemos una caracterización de la integrabilidad en el sentido de Riemann, que produce ...
An adaptive choice of primal constrains for BDDC domain decomposition algorithms
(2016-12-12)
An adaptive choice for primal spaces based on parallel sums is developed for BDDC deluxe methods and elliptic problems in three dimensions. The primal space, which forms the global, coarse part of the domain decomposition ...
Isometry groups of borel randomizations
(2018-08)
We study global dynamical properties of the isometry group of the Borel randomization of a separable complete structure. In particular, we show that if properties such as the Rohklin property, topometric generics, extreme ...
Correction to: The chirality theorem

A brief survey of Higgs bundles
Un estudio conciso de fibrados de Higgs
(2019-06)
Considering a compact Riemann surface of genus greater or equal than
two, a Higgs bundle is a pair composed of a holomorphic bundle over the
Riemann surface, joint with an auxiliar vector field, so-called Higgs field.
This ...
A basic model for the propagation of ideologies
(2022-11)
Ideas and ideologies move the world and are involved in almost every aspect of human life and society. This paper presents a mathematical model for the propagation of two different ideologies in a group of people that could ...
Aritmética para maestros: el número, su operatoria y su enseñanza
(1996)
Es un manual en el que se desarrolla, de una forma sencilla, una posible introducción del niño preescolar y escolar al campo del número y del cálculo aritmético. Se sugieren actividades que tienen una función didáctica ...
The Dirac operator on SU_q(2)
(2005)
We construct a 3^+ summable spectral triple (A(SU_q(2)),H,D) over the quantum group SU_q(2) which is equivariant with respect to a left and a right action of U_q(su(2)). The geometry is isospectral to the classical case ...
Sparse bounds for Bochner–Riesz multiplers
(2019)
The Bochner–Riesz multipliers are shown to satisfy a range of sparse bounds. The range of sparse bounds increases to the optimal range, as δ increases to the critical value, even assuming only partial information on the ...
