A course on Leavitt path algebras
(2015-10-05)En este libro se tratan las nociones básicas relacionadas con dichas álgebras. Se ven ejemplos, se clasifican las de dimensión finita, se caracterizan las simples y las puramente infinitas simples, obteniéndose el principio ... -
An approach to absolute valued algebras by reflections
(2013-12-11)This talk deals with the problem of the classification of the finite-dimensional absolute-valued algebras, with an special emphasis in the case of the dimension eight. -
Determinación algorítmica de estructuras Hopf Galois
(2018-10-15)La teoría Hopf-Galois es una generalización de la teoría de Galois. La clave es sustituir los grupos de Galois por álgebras de Hopf y la acción de Galois por una cierta “acción de Hopf” que actúa por endomorfismos. Este ... -
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 ... -
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 ... -
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 ... -
Sigma-maps on triangular algebras
(2018-01-30)Triangular algebras were introduced by Chase in the early 1960s. He ended up with these structures in the course of his study of the asymmetric behavior of semi-hereditary rings. Since their introduction, triangular ... -
Teoría de Hopf Galois: Introducción y enfoque aritmético
(2018-10-05)La teoría de Hopf Galois es una generalización de la teoría de Galois usando álgebras de Hopf, y surge en 1969 de la mano de S. U. Chase y M. E. Sweedler, con la idea de reemplazar el grupo de Galois de una extensión de ...
