Cracking isotropic and anisotropic relativistic spheres
Guillermo A. Gonzalez, Anamaria Navarro, Luis A. Nunez
We explore the influence of density fluctuations on isotropic and anisotropic configurations, extending the concept of cracking for general relativistic fluid spheres. This concept…
Comment on "Generalized black diholes"
V. S. Manko, J. D. Sanabria-Gómez
We show that a recent solution published by Cabrera-Munguia et al. is physically inconsistent since the quantity it involves does not have a correct limit .
Scale and shape dependent non-Gaussianity in the presence of inflationary vector fields
Juan P. Beltran Almeida, Yeinzon Rodriguez, Cesar A. Valenzuela-Toledo
We consider cosmological inflationary models in which vector fields play some role in the generation of the primordial curvature perturbation . Such models are interesting becau…
The inflationary origin of the Cold Spot anomaly
Juan C. Bueno Sanchez
Single-field inflation, arguably the simplest and most compelling paradigm for the origin of our Universe, is strongly supported by the recent results of the Planck satellite and t…
On the Schrödinger equations with isotropic and anisotropic fourth-order dispersion
Carlos Banquet, Elder J. Villamizar-Roa
This paper deals with the Cauchy problem associated to the nonlinear fourth-order Schrödinger equation with isotropic and anisotropic mixed dispersion. This model is given by the e…
