چکیده
|
Recently, lifting causal conditions of spacetime to coverings is considered by many authors as a technique in lorentzian geometry. in this paper, we discuss how to classify spacetimes by the covering spaces and show that causal pseudoconvexityconditions lift to its coverings for strongly causal spacetimes.
