Lanczos potentials and curvature-free connections aligned to a geodesic shear-free expanding null congruence
Fredrik Andersson
By the method of rho-integration we obtain all Lanczos potentials L_{ABCA'} of the Weyl spinor that, in a certain sense, are aligned to a geodesic shear-free expanding null congrue…

Integration of the GHP equations in spacetimes admitting a geodesic shear-free expanding null congruence
Fredrik Andersson
We perform a complete rho-integration of the GHP equations for all spacetimes that admit a geodesic shear-free expanding null congruence, whose Ricci spinor is aligned to the congr…
