G2 and the rolling ball
(2017-05-09)Understanding the exceptional Lie groups as the symmetry groups of simpler objects is a long-standing program in mathematics. Here, we explore one famous realization of the smallest exceptional Lie group, G2: Its Lie ... -
Geometric assumptions and variational tools in Lorentzian geometry
(2014-10-02)During the past years there has been a considerable amount of research related to the problem of geodesic connectedness of Lorentzian manifolds. In particular, some geometric sufficient conditions have been introduced so ... -
Geometries from structurable algebras and inner ideals
(2020-02-12)Se estudian ciertos tipos de geometrias en algebras estructurables via sus ideales internos abelianos. -
Gradings on classical Lie algebras via sesquilinear forms over graded-division algebras
(2022)En esta charla de aproximadamente una hora el profesor Dr. Mikhail V. Kochetov nos introduce en las últimas técnicas usadas para clasificar graduaciones sobre ciertas álgebras de Lie clásicas. Técnicas usadas en su monografía ... -
A gravitational collapse singularity theorem that improves Penrose's
(2020-03-09)The global hyperbolicity assumption present in gravitational collapse singularity theorems is in tension with the quantum mechanical phenomenon of black hole evaporation. In this work I show that the causality conditions ... -
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
Cañas Muñoz, Alejandro; Hidalgo, Rubén A.; Turiel-Sandin, Francisco Javier
; Viruel-Arbaizar, Antonio Angel (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
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, ... -

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 ...
