Symmetries of asymptotically flat axisymmetric space-times with null dust (English)
0 references
Symmetries of space-times with null dust field as a source compatible with asymptotic flatness are studied. It is shown that in an axially symmetric space-time with null dust field in which at least locally a smooth null infinity in the sense of Penrose exists, the only allowable additional Killing vector forming with the axial one a two-dimensional Lie algebra is a supertranslational Killing vector and the gravitational field is then nonradiative.
