Nuevos escenarios educativos en matemática discreta trabajando con JFLAPNew educational scenarios in discreet math working with JFLAP
(Universidad de La Guajira, 2020-06)
Las tecnologías de la información y la comunicación (TIC) permiten una mayor interactividad entre docentes y alumnos, y propician el surgimiento de nuevos escenarios para aprender. La humanidad se comunica con lenguajes ...
Cosmological horizons, Noether charges and entropy
(IOP Publishing, 2019-07-23)
It has recently been shown that, in the vicinity of their event horizons, black holes exhibit an infinite-dimensional symmetry. This symmetry captures relevant physical information about the black hole, and in particular ...
A characterization of the left exact categories whose exact completions are toposes
(Elsevier Science, 2003-02-01)
We characterize the categories with finite limits whose exact completions are toposes and discuss some examples and counter-examples.
Equivalence classes of exact module categories over graded tensor categories
(Taylor & Francis, 2020-10-04)
We describe equivalence classes of indecomposable exact module categories over a finite graded tensor category. When applied to a pointed fusion category, our results coincide with the ones obtained in [11].
Puntos fijos de acciones y funciones en 2-complejosFixed points of maps and actions on 2-complexes
(2019-03-12)
En esta tesis buscamos comprender cómo los invariantes algebraicos de un espacio X dan información acerca de la existencia de puntos fijos de una función o acción de un grupo en X, especialmente cuando X es de dimensión ...

Limits of quotients of bivariate real analytic functions
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2013-03-01)
Necessary and sufficient conditions for the existence of limits of the form lim (x,y)?(a,b)f(x, y)/g(x, y) are given, under the hypothesis that f and g are real analytic functions near the point (a, b), and g has an isolated ...
Group actions on 2-categories
(Springer, 2019-05)
We study actions of discrete groups on 2-categories. The motivating examples are actions on the 2-category of representations of finite tensor categories and their relation with the extension theory of tensor categories ...
Two examples of vanishing and squeezing in K1
(State University of New York, 2020-06)
Controlled topology is one of the main tools for proving the isomorphism conjecture concerning the algebraic K-theory of group rings. In this article we dive into this machinery in two examples: when the group is infinite ...
Numerical simulation of the flow around the ahmed vehicle model
(Planta Piloto de Ingeniería Química, 2009-10)
The unsteady flow around the Ahmed vehicle model is numerically solved for a Reynolds number of 4.25 million based on the model length. A viscous and incompressible fluid flow of Newtonian type governed by the Navier-Stokes ...
