Causal symmetries
A. García-Parrado, J. M. M. Senovilla
We define a new type of transformation for Lorentzian manifolds characterized by mapping every causal future-directed vector onto a causal future-directed vector. The set of all su…
Causal Relationship: a new tool for the causal characterization of Lorentzian manifolds
Alfonso García-Parrado, José M M Senovilla
We define and study a new kind of relation between two diffeomorphic Lorentzian manifolds called {\em causal relation}, which is any diffeomorphism characterized by mapping every c…
Causal Relations and their applications
Alfonso García-Parrado, José M. M. Senovilla
In this work we define and study the relations between Lorentzian Manifolds given by the diffeomorphisms which map causal future directed vectors onto causal future directed vector…
