On energy and its positivity in spacetimes with an expanding flat de Sitter background
Rodrigo Avalos, Eric Ling, Annachiara Piubello
The positive energy theorems are a fundamental pillar in mathematical general relativity. Originally proved by Schoen-Yau and later Witten, these theorems were established for asym…
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…
Geodesic motion around hairy black holes
A. Ramos, C. Arias, R. Ávalos +1
In a recent paper (Phys. Dark Univ. {\bf 31}, 100744 (2021)) it has been obtained new static black hole solutions with primary hairs by the Gravitational Decoupling. In this work w…
Reduced thin-sandwich equations on manifolds euclidean at infinity and on closed manifolds: existence and multiplicity
Rodrigo Avalos, Jorge H. Lira
The reduced thin-sandwich equations (RTSE) appear within Wheeler's thin-sandwich approach towards the Einstein constraint equations (ECE) of general relativity. It is known that th…
On the Cauchy Problem for Weyl-Geometric Scalar-Tensor Theories of Gravity
R. Avalos, I. P. Lobo, T. Sanomiya +1
In this paper, we analyse the well-posedness of the initial value formulation for particular kinds of geometric scalar-tensor theories of gravity, which are based on a Weyl integra…
On the embedding of Weyl manifolds
R. Avalos, F. Dahia, C. Romero
We discuss the possibility of extending different versions of the Campbell-Magaard theorem, which have already been established in the context of semi-Riemannian geometry, to the c…
