Alexandrov Theorem for 2+1 flat radiant spacetimes
Léo Brunswic
A classical Theorem of Alexandrov states that the map associating its boundary to a convex polyhdedron of the 3-dimensional Euclidean space is a bijection from the set of convex po…

Cauchy-Compact flat spacetimes with BTZ singularities
Léo Brunswic
The zoology of singularities for Lorentzian manifold is slightly more complicated than for Riemannian manifolds. Our present work study Cauchy-compact globally hyperbolic singular…

BTZ extensions of globally hyperbolic singular flat spacetimes
Léo Brunswic
Minkowski space is the local model of 3 dimensionnal flat spacetimes. Recent progress in the description of globally hyperbolic flat spacetimes showed strong link between Lorentzia…
