Groupoids and Steinberg Algebras
(2016-03-15)A groupoid is a generalisation of group in which composition is only partially defined. In first half of this talk, I will give an overview of groupoid theory and show how groupoids provide a unifying model for a number ... -
Groups as automorphisms of dessins d’enfants
(Springer, 2022-08-01)It is known that every finite group can be represented as the full group of automorphisms of a suitable compact dessin d’enfant. In this paper, we give a constructive and easy proof that the same holds for any countable ... -
Grupos p-locales finitos y grupos de cohomología
(2013-12-10)Definimos ciertos espacios topológicos llamados grupos p-locales finitos e introducimos una sucesión espectral que calcula su cohomología en ciertos casos, incluyendo algunos grupos p-locales finitos "exóticos". Presentaremos ... -
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
(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
(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
(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
(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 ... -
Más allá de Sylow.
(2023)Más allá de Sylow, están Hall y Carter con sus correspondientes subgrupos, conocidos por sus nombres respectivos. Y más allá está Gaschütz, quien de forma sorprendente dio una visión conjunta de todos ellos con sus envolturas ... -
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, ...
