Turbulence in the Ionized Gas of the Orion Nebula
S. J. Arthur, S. -N. X. Medina, W. J. Henney
In order to study the nature, origin, and impact of turbulent velocity fluctuations in the ionized gas of the Orion Nebula, we apply a variety of statistical techniques to observed…
Callan-Giddings-Harvey-Strominger vacuum in loop quantum gravity and singularity resolution
Alejandro Corichi, Javier Olmedo, Saeed Rastgoo
We study here a complete quantization of a Callan-Giddings-Harvey-Strominger (CGHS) vacuum model following loop quantum gravity techniques. Concretely, we adopt a formulation of th…
Characterizing Corson and Valdivia compact spaces
F. Casarrubias-Segura, S. García-Ferreira, R. Rojas-Hernández
We give a new characterization of Valdivia compact spaces: A compact space is Valdivia if and only if it has a dense commutatively monotonically retractable subspace. This result s…
Landau-Khalatnikov-Fradkin transformations in Reduced Quantum Electrodynamics
A. Ahmad, J. J. Cobos-Martínez, Y. Concha-Sánchez +1
We derive the Landau-Khalatnikov-Frandkin transformation (LKFT) for the fermion propagator in quantum electrodynamics (QED) described within a brane-world inspired framework where…
Veech groups of infinite genus surfaces
Camilo Ramirez Maluendas, Ferran Valdez
We show that every countable subgroup without contracting elements is the Veech group of a tame translation surface of infinite genus, for infinitely…
The Ellis semigroup of a nonautonomous discrete dynamical system
S. García-Ferreira, M. Sanchis
We introduce the {\it Ellis semigroup} of a nonautonomous discrete dynamical system when is a metric compact space. The underlying set of this semigroup is t…
