On constructing purely affine theories with matter
Autor: D. E. Liebscher, Jorge L. Cervantes-Cota
We explore ways to obtain the very existence of a space-time metric from an action principle that does not refer to it a priori. Although there are reasons to believe that only a non-local theory can viably achieve this goal, we investigate here loca

The electrostatics of Einstein’s unified field theory
Autor: Salvatore Antoci, L. Mihich, D.-E. Liebscher
Publikováno v: General relativity and gravitation 37 (2005): 1191–1203.

When sources are added at their right-hand sides, and g_{(ik)} is a priori assumed to be the metric, the equations of Einstein's Hermitian theory of relativity were shown to allow for an exact solution that describes the general electrostatic field o

Editor's Note: On the Gravitational Field of a Mass Point According to Einstein's Theory by K. Schwarzschild
Autor: S. Antoci, D.-E. Liebscher
Publikováno v: General Relativity and Gravitation. 35:945-950
We comment on the famous paper by Karl Schwarzschild from 1916, which is reprinted in the present issue.

Deriving the spin rate/orientation from the quiescent spacecraft ABRIXAS using optical observations
Autor: Jochen Greiner, P. Friedrich, Paul D. Maley, B. Lübke-Ossenbeck, D. E. Liebscher, Günther Hasinger
Publikováno v: Acta Astronautica. 48:469-478
With the loss of the battery system of ABRIXAS shortly after launch and consequent absence of telemetry, there was urgent need to determine ABRIXAS' spin rate and orientation in order to assess the possibility of re-establishing telemetry during peri

Aberration and relativity
Autor: P. Brosche, D.-E. Liebscher
Publikováno v: Astronomische Nachrichten: News in Astronomy and Astrophysics. 319:309-318
The aberration of starlight seems to be one of the simplest phenomena of astronomical observation. However, the story of misunderstandings is long and lasts till now. It is nearly forgotten that the problem of stellar aberration was the cornerstone o

Some more methods and exact solutions to solve Kaluza-Klein cosmologies
Autor: A. G. Polnarev, D.-E. Liebscher, U. Bleyer
Publikováno v: Classical and Quantum Gravity. 8:477-491
The authors consider general methods to solve the equations for Kaluza-Klein cosmological models by using the formal identity of these equations with those of a relativistic point particle in a scalar field. The formal scalar field is given by the ph

Mixed metric perturbations in Kaluza-Klein cosmologies
Autor: D.-E. Liebscher, U. Bleyer, A. G. Polnarev
Publikováno v: Il Nuovo Cimento B. 106:107-122
We consider metric perturbations of Kaluza-Klein cosmological models filled with phenomenological matter. We find the exact solution for the development in time of the mixed perturbations, which have one index in the ordinary and one in the internal

A way for appending sources at the right-hand sides of the field equations of Einstein's unified field theory is recalled. Two exact solutions endowed with point sources in equilibrium are shown, and their physical meaning is discussed.
