Horizons in Robinson-Trautman space-times
W. Natorf, J. Tafel
The past quasi-local horizons in vacuum Robinson-Trautman spacetimes are described. The case of a null (non-expanding) horizon is discussed. It is shown that the only Robinson-Trau…
Symmetries of the Robinson-Trautman equation
Wlodzimierz Natorf, Jacek Tafel
We study point symmetries of the Robinson--Trautman equation. The cases of one- and two-dimensional algebras of infinitesimal symmetries are discussed in detail. The corresponding…
New vacuum Robinson--Trautman metrics
Wlodzimierz Natorf
This paper has been withdrawn by the author. The metrics presented are known since 1969 (and are referred to as C-metrics)
Kerr--Schild metrics and gravitational radiation
Włodzimierz Natorf
We describe conditions assuring that the Kerr--Schild type solutions of Einstein equations with pure radiation fields are asymptotically flat at future null infinity. Such metrics…
