Generalized Minkowski Theorem for Tetrahedra in and
This paper establishes a generalized Minkowski theorem for constant-curvature Lorentzian spaces by proving that four non-trivial holonomies uniquely reconstruct a strictly convex tetrahedron in de Sitter or anti-de Sitter space under specific closure and convexity conditions, while also characterizing the resulting polar-dual projective tetrahedra and recovering classical Euclidean and hyperbolic reconstruction results in the spacelike sector.
