Republication of: The geometry of free fall and light propagation
This is a reprinting of the paper by Jürgen Ehlers, Felix Pirani and Alfred Schild, first published in 1972 in a separate volume containing articles written in hounour of J. L. Synge. The original…
Dynamics of extended bodies in general relativity center-of-mass description and quasirigidity
- J. Ehlers, E. Rudolph
- Physics
- 1 March 1977
Dixon's approach to describe the dynamics of extended bodies in metric theories of gravity is elaborated. The exact, general relation between the center-of-mass 4-velocity and the 4-momentum is…
Isotropic Solutions of the Einstein‐Liouville Equations
The gravitational field generated by a gas whose one‐particle distribution function obeys the Liouville equation is examined under the following assumptions: First, the distribution is locally…
A phase-space representation of Friedmann-Lemaitre universes containing both dust and radiation and the inevitability of a big bang
- J. Ehlers, W. Rindler
- Physics
- 1 May 1989
Les univers de Friedmann-Lemaitre contenant de la poussiere et du rayonnement sont classes et leurs histoires sont tracees comme des orbites dans un espace de phase S a 3 dimensions, refletant la…
