Quantization of Interacting Non-Relativistic Open Strings using Extended Objects
P. J. Arias, N. Bolívar, E. Fuenmayor +1
Non-relativistic charged open strings coupled with Abelian gauge fields are quantized in a geometric representation that generalizes the Loop Representation. The model comprises op…
Thermo--inertial bouncing of a relativistic collapsing sphere: A numerical model
L. Herrera, A. Di Prisco, W. Barreto
We present a numerical model of a collapsing radiating sphere, whose boundary surface undergoes bouncing due to a decreasing of its inertial mass density (and, as expected from the…
Gravitational radiation, vorticity and the electric and magnetic part of Weyl tensor
L. Herrera, N. O. Santos, J. Carot
The electric and the magnetic part of the Weyl tensor, as well as the invariants obtained from them, are calculated for the Bondi vacuum metric. One of the invariants vanishes iden…
A notion of selective ultrafilter corresponding to topological Ramsey spaces
Jose Mijares
We introduce the relation of "almost-reduction" in an arbitrary topological Ramsey space R, as a generalization of the relation of "almost-inclusion" on the space of infinite sets…
Parametrizing the abstract Ellentuck theorem
Jose Mijares
We give a parametrization with perfect sets of the abstract Ellentuck theorem. The main tool for achieving this goal is a sort of parametrization of an abstract version of the Nash…
Homological matrices
Edmundo Castillo, Rafael Diaz
We define homological matrices, construct examples of one-dimension restricted homological quantum field theories, and show a relationship between the two theories.
A self-similar dynamics in viscous spheres
W. Barreto, J. Ovalle, B. Rodriguez
We study the evolution of radiating and viscous fluid spheres assuming an additional homothetic symmetry on the spherically simmetric space--time. We match a very simple solution t…
Feynman-Jackson integrals
Rafael Diaz, Eddy Pariguan
We introduce perturbative Feynman integrals in the context of q-calculus generalizing the Gaussian q-integrals introduced by Diaz and Teruel. We provide analytic as well as combina…
Combinatorial approach to generalized Bell and Stirling numbers and boson normal ordering problem
M A Mendez, P Blasiak, K A Penson
We consider the numbers arising in the problem of normal ordering of expressions in canonical boson creation and annihilation operators. We treat a general form of a boson string w…
Estimation in autoregressive models with Markov regime
Ricardo Ríos, Luis Rodríguez
In this paper we derive the consistency of the penalized likelihood method for the number state of the hidden Markov chain in autoregressive models with Markov regimen. Using a SAE…
A general relativistic effect in quasi-spherical objects as the possible origin of relativistic jets
L. Herrera, N. O. Santos
Based on recently reported results, we present arguments that sign changes in proper acceleration of test particles on the symmetry axis and close to the r=2M surface of quasi-sphe…
On the arithmetic product of combinatorial species
Manuel Maia, Miguel Mendez
We introduce two new binary operations with combinatorial species; the arithmetic product and the modified arithmetic product. The arithmetic product gives combinatorial meaning to…
A Statistical view of Iterative Methods for Linear Inverse Problems
Ana K. Fermin, Carenne Ludena
In this article we study the problem of recovering the unknown solution of a linear ill-posed problem, via iterative regularization methods. We review the problem of projection-reg…
On -differential graded algebras
Mauricio Angel, Rafael Díaz
We introduce the concept of -differential graded algebras (N-dga), and study the moduli space of deformations of the differential of a N-dga. We prove that it is controlled by w…
Loop Equations in Abelian Gauge Theories
Cayetano Di Bartolo, Lorenzo Leal, Francisco Peña
The equations obeyed by the vacuum expectation value of the Wilson loop of Abelian gauge theories are considered from the point of view of the loop-space. An approximative scheme f…
Controlling soliton explosions
J. A. Gonzalez, A. Bellorin, L. E. Guerrero
We investigate the dynamics of solitons in generalized Klein-Gordon equations in the presence of nonlinear damping and spatiotemporal perturbations. We will present different mecha…
Cylindrical Collapse and Gravitational Waves
L. Herrera, N. O. Santos
We study the matching conditions for a collapsing anisotropic cylindrical perfect fluid, and we show that its radial pressure is non zero on the surface of the cylinder and proport…
Neutral perfect fluids of Majumdar-type in general relativity
V. Varela
We consider the extension of the Majumdar-type class of static solutions for the Einstein-Maxwell equations, proposed by Ida to include charged perfect fluid sources. We impose the…
