Abstract
The zoology of singularities for Lorentzian manifold is slightly more complicated than for Riemannian manifolds. Our present work study Cauchy-compact globally hyperbolic singular flat spacetimes with extreme BTZ-like singular lines. We use the notion of BTZ-extension of a singular spacetime introduced in a previous paper to give a description of Moduli spaces of such manifolds in term of common Teichm{\"u}ller spaces. This description is used to construct convex polyhedral cauchy-surface in Cauchy-compact flat spacetimes with BTZ.
