text:
A Picard horn, also called the Picard topology or Picard model, is one of the oldest known hyperbolic 3-manifolds, first described by Émile Picard in 1884. The manifold is the quotient of the upper half-plane model of hyperbolic 3-space by the projective special linear group, PSL 2 . It was proposed as a model for the shape of the universe in 2004. The term "horn" is due to pseudosphere models of hyperbolic space.
