Atlas of three body mean motion resonances in the Solar System
Tabaré Gallardo
We present a numerical method to estimate the strengths of arbitrary three body mean motion resonances between two planets in circular coplanar orbits and a massless particle in an…
Stability and magnetism in complex multivacancy graphene systems
Ricardo Faccio, Alvaro W. Mombrú
This work is focused in the stability and magnetic properties of complex graphene multivacancy systems, studied by Density Functional Theory calculations. The removal of a sequence…
An introduction to spherically symmetric loop quantum gravity black holes
Rodolfo Gambini, Jorge Pullin
We review recent developments in the treatment of spherically symmetric black holes in loop quantum gravity. In particular, we discuss an exact solution to the quantum constraints…
Stability of multivacancies in graphene
Ricardo Faccio, Alvaro W. Mombrú
The stability of graphene multivacancy systems is studied using Density Functional Theory (DFT) calculations. This work describes the evolution of the energy of formation per carbo…
Sub-Doppler resonances in the back-scattered light from random porous media infused with Rb vapor
S. Villalba, A. Laliotis, L. Lenci +3
We report on the observation of sub-Doppler resonances on the back-scattered light from a random porous glass medium with rubidium vapor filling its interstices. The sub-Doppler sp…
The Kardar-Parisi-Zhang equation with spatially correlated noise: a unified picture from nonperturbative renormalization group
Thomas Kloss, Léonie Canet, Bertrand Delamotte +1
We investigate the scaling regimes of the Kardar-Parisi-Zhang equation in the presence of spatially correlated noise with power law decay in Fourier space, usin…
On the nature of the new group LB1
Alcides Garat
The new local group LB1 introduced previously will be studied and reviewed in detail, depicting its unique nature that makes it a new group in fundamental physics. It will be made…
Almost involutive Hopf algebras
Andrés Abella, Walter Ferrer Santos
We define the concept of \emph{companion automorphism} of a Hopf algebra as an automorphism : --where denotes the antipode--. A Hopf algebra is…
Robust Multimodal Graph Matching: Sparse Coding Meets Graph Matching
Marcelo Fiori, Pablo Sprechmann, Joshua Vogelstein +2
Graph matching is a challenging problem with very important applications in a wide range of fields, from image and video analysis to biological and biomedical problems. We propose…
N-expansive homeomorphisms on surfaces
Alfonso Artigue, Maria José Pacifico, José Vieitez
We exploit the techniques developed in [Le] to study N-expansive homeomorphisms on surfaces. We prove that when f is a 2-expansive homeomorphism defined on a compact boundaryless s…
Quasispecies dynamics on a network of interacting genotypes and idiotypes: Formulation of the model
Valmir C. Barbosa, Raul Donangelo, Sergio R. Souza
A quasispecies is the stationary state of a set of interrelated genotypes that evolve according to the usual principles of selection and mutation. Quasispecies studies have invaria…
Thermoconvective structure dynamics in horizontal Homeotropic Nematics films heated from above
I. Bove, J. Salán
Homeotropic Nematic Liquid Crystal heated from above present convective Rayleigh-Benard instability for applied thermal gradients greater than Tc. This threshold increase with t…
Modelling magnetism of C at O and B monovacancies in graphene
T. P. Kaloni, M. Upadhyay Kahaly, R. Faccio +1
The presence of defects can introduce important changes in the electronic structure of graphene, leading to phenomena such as C magnetism. In addition, vacancies are reactive and p…
Distinguishing the effects of internal and forced atmospheric variability in climate networks
J. Ignacio Deza, Cristina Masoller, Marcelo Barreiro
The fact that the Earth climate is a highly complex dynamical system is well-known. In the last few decades a lot of effort has been focused on understanding how climate phenomena…
Three-point correlation functions in Yang-Mills theory
Marcela Pelaez, Matthieu Tissier, Nicolas Wschebor
We investigate the three-point correlation functions of Yang-Mills theory in the Landau gauge, with a particular emphasis on the infrared regime. The effect of the Gribov copies is…
Yang-Mills correlators at finite temperature: A perturbative perspective
U. Reinosa, J. Serreau, M. Tissier +1
We consider the two-point correlators of Yang-Mills theories at finite temperature in the Landau gauge. We employ a model for the corresponding Yang-Mills correlators based on the…
A few remarks on partially hyperbolic diffeomorphisms of isotopic to Anosov
Rafael Potrie
We show that a strong partially hyperbolic diffeomorphism of isotopic to Anosov has a unique quasi-attractor. Moreover, we study the entropy of the diffeomorphism re…
The Jamming Constant of Uniform Random Graphs
Paola Bermolen, Matthieu Jonckheere, Pascal Moyal
By constructing jointly a random graph and an associated exploration process, we define the dynamics of a "parking process" on a class of uniform random graphs as a measure-valued…
Dynamical symmetry breaking in Yang-Mills geometrodynamics
Alcides Garat
We will analyze through a first order perturbative formulation the local loss of symmetry when a source of non-Abelian Yang-Mills and gravitational fields interacts with an externa…
A Report on Realizability
Walter Ferrer Santos, Mauricio Guillermo, Octavio Malherbe
Besides recalling the basic definitions of Realizability Lattices, Abstract Krivine Structures, Ordered Combinatory Algebras and Tripos and reviewing its relationships, we propose…
Some constructions of compact quantum groups
Andrés Abella, Walter Ferrer Santos, Mariana Haim
The purpose of this paper is to consider some basic constructions in the category of compact quantum groups --for example de case of extensions, of Drinfeld twists, of matched pair…
On solutions for derivations of a Noetherian k-algebra and local simplicity
Rene Baltazar, Ivan Pan
We introduce a general notion of solution for a Noetherian differential -algebra and study its relationship with simplicity, where k is an algebraically closed field; then we an…
Low dimensional bifurcations of snap-back repellors
Alfonso Artigue
We study the relationship between homoclinic orbits associated to repellors, usually called snap-back repellors, and expanding sets of smooth endomorphisms. Critical homoclinic orb…
Resiliently evolving supply-demand networks
Nicolás Rubido, Celso Grebogi, Murilo S. Baptista
The ability to design a transport network such that commodities are brought from suppliers to consumers in a steady, optimal, and stable way is of great importance for nowadays dis…
