Paper constructs two series of Lorentz bi-quotients from polyhedra.
This paper standardizes Cheeger deformations on fiber bundles with compact groups.
The main result of this paper is a construction of fundamental domains for certain group actions on Lorentz manifolds of constant curvature. We consider the simply connected Lie group G~, the universal cover of the group SU(1,1) of orientation-preserving isometries of the hyperbolic plane. The Killing form on the Lie g…
