Nonstandard Lorentz space forms
Nonstandard Lorentz space forms
In their recent paper [8], Kulharni and Raymond show that a closed 3-manifold which admits a complete Lorentz metric of constant curvature 1 (henceforth called a complete Lorentz structure) must be Seifert fibered over a hyperbolic base.Furthermore on every such Seifert fibered 3-manifold with nonzero Euler class they construct such …
