Causal completion of a globally hyperbolic conformally flat spacetime

Rym Smaï

In [6], Geroch, Kronheimer and Penrose introduced a way to attach ideal points to a spacetime M , defining the causal completion of M. They established that this is a topological s…

Enveloping space of a globally hyperbolic conformally flat spacetime

Rym Smaï

We prove that any simply-connected globally hyperbolic conformally flat spacetime V can be conformally embedded in a bigger conformally flat spacetime, called enveloping space of V…

Timelike Hilbert geometry of the spherical simplex

Athanase Papadopoulos, Sumio Yamada

We prove the following result on the timelike spherical Hilbert geometry of simplices: Let be a simplex on the 2-sphere and the antipodal simplex. We show that th…
