Bi-conformal vector fields and their applications
Alfonso García-Parrado, José M. M. Senovilla
We introduce the concept of bi-conformal transformation, as a generalization of conformal ones, by allowing two orthogonal parts of a manifold with metric $\G$ to be scaled by diff…
General study and basic properties of causal symmetries
Alfonso García-Parrado, José M. M. Senovilla
We fully develop the concept of causal symmetry introduced in Class. Quant. Grav. 20 (2003) L139. A causal symmetry is a transformation of a Lorentzian manifold (V,g) which maps ev…
Causal symmetries
Alfonso García-Parrado, José M. M. Senovilla
Based on the recent work \cite{PII} we put forward a new type of transformation for Lorentzian manifolds characterized by mapping every causal future-directed vector onto a causal…
