One-dimensional subspaces of the Chiral Equations
I. A. Sarmiento-Alvarado, Petra Wiederhold, Tonatiuh Matos
In this work we find solutions of the ()-dimensional Einstein Field Equations (EFE) with commuting Killing vectors in vacuum. In the presence of Killing vectors, the E…
Cosmic acceleration from topological considerations II: Fiber bundles
Maribel Hernández Márquez, Tonatiuh Matos Chassin, Petra Wiederhold
In this work we study an alternative topological model for explaining the observed acceleration of space-time, we answer the question of whether this acceleration could be a conseq…
Relative Convex Hull Determination from Convex Hulls in the Plane
P. Wiederhold, H. Reyes
A new algorithm for the determination of the relative convex hull in the plane of a simple polygon A with respect to another simple polygon B which contains A, is proposed. The rel…
Class of Einstein-Maxwell-Dilaton-Axion Space-Times
Tonatiuh Matos, Galaxia Miranda, Ruben Sanchez-Sanchez +1
We use the harmonic maps ansatz to find exact solutions of the Einstein-Maxwell-Dilaton-Axion (EMDA) equations. The solutions are harmonic maps invariant to the symplectic real gro…
Scalar Field Dark Matter and Galaxy Formation
Miguel Alcubierre, F. Siddhartha Guzman, Tonatiuh Matos +3
We present a general description of the scalar field dark matter (SFDM) hypothesis in the cosmological context. The scenario of structure formation under such a hypothesis is based…
Galactic Collapse of Scalar Field Dark Matter
Miguel Alcubierre, F. Siddhartha Guzman, Tonatiuh Matos +3
We present a scenario for galaxy formation based on the hypothesis of scalar field dark matter. We interpret galaxy formation through the collapse of a scalar field fluctuation. We…
