How to measure spatial distances?
Hans - Juergen Schmidt
The use of time--like geodesics to measure temporal distances is better justified than the use of space--like geodesics for a measurement of spatial distances. We give examples whe…

Classical mechanics with lapse
Hans - Juergen Schmidt
Mechanics is developed over a differentiable manifold as space of possible positions. Time is considered to fill a one--dimensional Riemannian manifold, so having the metric as lap…

Inhomogeneous Cosmological Models with Homogeneous Inner Hypersurface Geometry
M. Rainer, H. -J. Schmidt
Space-times which allow a slicing into homogeneous spatial hypersurfaces generalize the usual Bianchi models. One knows already that in these models the Bianchi type may change wit…
