Cardinality of the Ellis semigroup on compact metric countable spaces

S. Garcia-Ferreira, Y. Rodriguez-Lopez, C. Uzcategui

Let be the Ellis semigroup of a dynamical system where is a compact metric space. We analyze the cardinality of for a compact countable metric space $…

Self-similar and charged spheres in the free-streaming approximation

W. Barreto, L. Rosales

We evolve nonadiabatic charged spherical distributions of matter. Dissipation is described by the free-streaming approximation. We match a self-similar interior solution with the R…

Nonadiabatic charged spherical evolution in the postquasistatic approximation

L. Rosales, W. Barreto, C. Peralta +1

We apply the postquasistatic approximation, an iterative method for the evolution of self-gravitating spheres of matter, to study the evolution of dissipative and electrically char…

Heat flow in the postquasistatic approximation

B. Rodríguez-Mueller, C. Peralta, W. Barreto +1

We apply the postquasistatic approximation to study the evolution of spherically symmetric fluid distributions undergoing dissipation in the form of radial heat flow. For a model w…

Self--similar and charged radiating spheres: An anisotropic approach

W. Barreto, B. Rodríguez, L. Rosales +1

Considering charged fluid spheres as anisotropic sources and the diffusion limit as the transport mechanism, we suppose that the inner space--time admits self--similarity. Matching…

Equation of state and transport processes in self--similar spheres

W. Barreto, C. Peralta, L. Rosales

We study the effect of transport processes (diffusion and free--streaming) on a collapsing spherically symmetric distribution of matter in a self--similar space--time. A very simpl…

The Gardner Category and Non-local Conservation Laws for N=1 Super KdV

S. Andrea, A. Restuccia, A. Sotomayor

The non-local conserved quantities of N=1 Super KdV are obtained using a complete algebraic framework where the Gardner category is introduced. A fermionic substitution semigroup a…

The 3-dimensional Einstein-Klein-Gordon system in characteristic numerical relativity

W. Barreto, A. Da Silva, R. Gomez +3

We incorporate a massless scalar field into a 3-dimensional code for the characteristic evolution of the gravitational field. The extended 3-dimensional code for the Einstein--Klei…

Supersymmetric exact sequence, heat kernel and super KdV hierarchy

S. Andrea, A. Restuccia, A. Sotomayor

We introduce the free N=1 supersymmetric derivation ring and prove the existence of an exact sequence of supersymmetric rings and linear transformations. We apply necessary and suf…

Radiating fluid spheres in the effective variables approximation

W. Barreto, B. Rodríguez, H. Martínez

We study the evolution of spherically symmetric radiating fluid distributions using the effective variables method, implemented {\it ab initio} in Schwarzschild coordinates. To ill…
