Homeomorphism groups of the cube and other n-manifolds
(2016-04-25)In this talk, the structure of the homeomorphism group of the cube is presented. Applications to the homeomorphism groups of other n-manifolds are also treated. -
Homotopy nilpotency and co-nilpotency of spaces
(2020-03-11)We review known and state some new results on homotopy nilpotency and co-nilpotency of spaces. Next, we take up the systematic study of homotopy nilpotency of homogenous spaces G/K for a Lie group G and its closed subgroup ... -
Incidence algebras. Overview
(2015-05-13)In his celebrated paper of 1964, "On the foundations of combinatorial theory I: Theory of Möbius Functions" Gian-Carlo Rota defined an incidence algebra as a tool for solving combinatorial problems. Incidence algebra is a ... -
Infinite-Dimensional Diagonalization
(2015-05-29)Let V be an arbitrary vector space over a field K, and let End(V) be the ring of all K-linear transformations of V. We characterize the diagonalizable linear transformations in End(V), as well as the (simultaneously) ... -
Infinity structures and higher products in rational homotopy theory
Moreno-Fernandez, Jose Manuel
(UMA Editorial, 2018)
Rational homotopy theory classically studies the torsion free phenomena in the homotopy category of topological spaces and continuous maps. Its success is mainly due to the existence of relatively simple algebraic models ... -
Iniciación a la espectroscopía de meteoros dentro de la Red de Detección de la Universidad de Málaga y de la Sociedad Malagueña de Astronomía
Castellon-Serrano, Alberto; Lopez-Ramirez, Maria Rosa (2021-10-11)
Se describe el método seguido para obtener espectros de meteoros con la estación de El Torcal incluida en la Red de Bólidos y Meteros UMA/SMA y el proceso de análisis de los mismos. -
Jordan elements in Lie algebras and inner ideals in the skew elements of prime rings with involution
(Servicio de Publicaciones y Divulgación Científica, 2015)* El capítulo 1 introduce resultados esenciales sobre los elementos skew de un anillo primo, necesarios en los capítulos 3 y 4. * En el capítulo 2 se demuestra que en un álgebra de Lie L libre de torsión 6, si a y b son ... -
Jordan-lie inner ideals of finite dimensional associative algebras
(2017-06-15)Any associative ring A becomes a Lie ring A(−) under [x, y] = xy−yx. Let A(1) = [A, A] be the derived subalgebra of A(−) and let Z be its center. In the early 1950s Herstein initiated a study of Lie ideals of A in case ... -
KV. Cohomology and some applications
(2020-02-24)Two versions of the KV-cohomology are presented and some algebraic and geometrical applications are given. We will see some applications to stochastic manifold. As a consequence, we can apply these ideas in Lorentzian ... -
L-InfinityAlgebras, Cohomology and M-Theory
(2017-05-12)In this introduction for topologists, we explain the role that extensions of L-infinity algebras by taking homotopy fibers plays in physics. This first appeared with the work of physicists D'Auria and Fre in 1982, ... -
La Red de Detección de Bólidos y Meteoros de la Universidad de Málaga y de la Sociedad Malagueña de Astronomía
Castellon-Serrano, Alberto (2019-12-11)
En la ponencia se presenta el estado actual de la Red de Detección de Bólidos y Meteoros de la Universidad de Málaga y la Sociedad Malagueña de Astronomía, el material utilizado para las instalaciones, el software propio ... -
Leavitt path algebras and the IBN property
(2016-12-21)A ring has invariant basis number property (IBN) if any two bases of a finitely generated free module have the same number of elements. In 1960's Leavitt constructed examples of rings R without IBN, more precisely for any ... -
Leavitt Path algebras via partial skew ring theory
(2018-04-17)We will introduce the theory or partial actions of groups and their associated algebras. As an example we will realize the Leavitt path algebra associated with a graph as a partial skew group ring. To finish, we will ... -
Lie models of classifying fibrations.
(UMA Editorial, 2023)En el ámbito de la Teoría de Homotopía Racional, los recientemente desarrollados modelos de Lie, permiten la modelización de espacios topológicos no simplemente conexos. En esta tesis se utiliza esta nueva técnica para ... -
Lie models of homotopy automorphism monoids and classifying fibrations
Félix, Yves; Fuentes Rumí, Mario; Murillo-Mas, Aniceto (Elsevier, 2022-06-25)
Given X a finite nilpotent simplicial set, consider the classifying fibrations X → B aut∗ G(X) → B autG(X) and X → Z → B aut∗ π (X) where G and π denote, respectively, subgroups of the free and pointed homotopy classes ... -
Massey products and higher operations
(2023-01-25)It was long believed that Massey products in the cohomology of a differential graded associative algebra were determined by the higher operations on a minimal A-infinity model. This was disproved by Buijs, Moreno-Fernández, ... -

Maximal surfaces and graphs in a Lorentzian product -RxM
(2015-02-26)We will present several results for maximal surfaces in a Lorentzian product manifold -R×M. The main purpose is to characterize the slices as complete maximal surfaces satisfying a comparison between the growth of lenght ... -
