The interior solution of axially symmetric, stationary and rigidly
  rotating dust configurations
  It is shown that the interior solution of axially symmetric, stationary and
rigidly rotating dust configurations is completely determined by the mass
density along the axis of rotation. The particularly interesting case of a mass
density, which is cylindrical symmetric in the interior of the dust
configuration, is presented. Among other things, this proves the non-existence
of homogeneous dust configurations.
