A course on Leavitt path algebras
Siles-Molina, Mercedes
(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. -
Categorías tensoriales, álgebras y superálgebras
(2022)After reviewing the basic definitions of tensor categories and the notion of semisimplification of symmetric tensor categories, it will be shown how the semisimplification of the category of representations of the cyclic ... -
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
Sanchez-Ortega, Juana; Repka, Joe; Martin-Gonzalez, Candido (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 ... -
The Talented monoid of a graph and its connections with the Leavitt path algebra
(2022)In this talk, we introduce an algebraic entity arising from a directed graph - the talented monoid. The talented monoid has an interesting relationship with the Leavitt path algebra. In fact, the group completion of the ...
