Interacting cosmic fluids and phase transitions under a holographic modeling for dark energy
Samuel Lepe, Francisco Pena
We discuss the consequences of possible sign changes of the -function which measures the energy transference between dark energy and dark matter. We investigate this scenario fr…
Families of Riemann Surfaces, Uniformization and Arithmeticity
Gabino González-Diez, Sebastián Reyes-Carocca
A consequence of the results of Bers and Griffiths on the uniformization of complex algebraic varieties is that the universal cover of a family of Riemann surfaces, with base and f…
A remark on the decomposition of the Jacobian variety of Fermat curves of prime degree
Ruben A. Hidalgo, Rubi E. Rodriguez
Recently, Barraza-Rojas have described the action of the full automorphisms group on the Fermat curve of degree , for a prime integer, and obtained the group algebra decompo…
Transformation of vector beams with radial and azimuthal polarizations in biaxial crystals
Alex Turpin, Asticio Vargas, Angel Lizana +5
We present both experimentally and theoretically the transformation of radially and azimuthally polarized vector beams when they propagate through a biaxial crystal and are transfo…
Chiral-Symmetry Breaking in Pseudo Quantum Electrodynamics at Finite Temperature
Leandro O. Nascimento, Van Sérgio Alves, Francisco Peña +2
We use the Schwinger-Dyson equations in the presence of a thermal bath, in order to study chiral symmetry breaking in a system of massless Dirac fermions interacting through pseudo…
Riemannian and Sub-Riemannian geodesic flows
Mauricio Godoy Molina, Erlend Grong
In the present paper we show that the geodesic flows of a sub-Riemannian metric and that of a Riemannian extension commute if and only if the extended metric is parallel with respe…
