Shear-free perfect fluids with divergence free magnetic Weyl curvature
Department of Mathematical Analysis, University of Ghent, Galglaan 2, Ghent, Belgium
We discuss shear-free perfect fluids which obey a barotropic equation of state and for which the magnetic part of the Weyl tensor with respect to the fluid congruence is divergence-free. We show that for a large class of equations of state these fluids are either non-expanding or non-rotating and we present a classification of the resulting non-expanding solutions.
