A fractional matter sector for general relativity
J. Palacios, A. Di Teodoro, E. fuenmayor +1
In this work, we construct a fractional matter sector for general relativity. In particular, we propose a suitable fractional anisotropy function relating both the tangential and r…
A vacuum solution of modified Einstein equations based on fractional calculus
A. Di Teodoro, E. Contreras
In this work, we construct a modified version of the Einstein field equations for a vacuum and spherically symmetric spacetime in terms of the Riemann-Louville fractional derivativ…
Double relativistic master polytrope for anisotropic matter
P. León, E. Fuenmayor, E. Contreras
We present a detailed analysis of a general relativistic static spherical symmetric distribution in which both the radial and tangential pressures follow a master polytropic equati…
A static and spherically symmetric hairy black hole in the framework of the Gravitational Decoupling
R. Avalos, P. Bargueño, E. Contreras
In this work we construct a static and spherically symmetric black hole geometry supported by a family of generic mono-parametric sources thorough the Gravitational Decoupling. The…
Anisotropic star models in the context of vanishing complexity
C. Arias, E. Contreras, E. Fuenmayor +1
We use the definition of complexity for static and self--gravitating objects to build up three physical general relativistic anisotropic models fulfilling the vanishing complexity…
Traversable wormholes with like--Casimir complexity supported with arbitrarily small amount of exotic matter
R. Ávalos, E. Fuenmayor, E. Contreras
In this work we construct traversable wormholes geometries in the framework of the complexity factor. We provide the redshift function of a Casimir traversable wormhole which, in c…
Uncharged and charged anisotropic like--Durgapal stellar model with vanishing complexity
E. Contreras, E. Fuenmayor, G. Abellán
In this work we use the vanishing complexity factor as a supplementary condition to construct uncharged and charged like--Durgapal models. We provide the component of the…
Construction of a traversable wormhole from a suitable embedding function
A. Rueda, R. Ávalos, E. Contreras
In this work, we construct a traversable wormhole by providing a suitable embedding function ensuring the fulfilling of the flaring--out condition. The solution contains free param…
Complexity factor for black holes in the framework of the Newman-Penrose formalism
P. Bargueño, E. Fuenmayor, E. Contreras
In this work, we introduce the {\it complexity factor} in the context of self--gravitating fluid distributions for the case of black holes by employing the Newman-Penrose formalism…
A simple protocol to construct solutions with vanishing complexity by Gravitational Decoupling
E. Contreras, Z. Stuchlik
In this work we develop a simple protocol to construct interior solutions through Gravitational Decoupling by the Minimal Geometric Deformation extended satisfying the vanishing co…
Borromean surgery equivalence of spin 3-manifolds with boundary
Eva Contreras, Kazuo Habiro
Matveev introduced Borromean surgery on 3-manifolds, and proved that the equivalence relation on closed, oriented 3-manifolds generated by Borromean surgeries is characterized by t…
