Title
Shear- free perfect fluids with solenoidal magnetic curvature and a γ-law equation of state
We show that shear-free perfect fluids obeying an equation of state p = (γ − 1)μ are non-rotating or non-expanding under the assumption that the spatial divergence of the magnetic part of the Weyl tensor is zero.
