Algebraic aspects of general non-twisting and shear-free spacetimes
Švarc, R; Podolský, J.
The algebraic structure, given by a null alignment of the Weyl tensor, of expanding
Robinson-Trautman and non-expanding Kundt geometries is analyzed in an arbitrary
dimension. Conditions for all possible algebraic types are identified in closed form. Since
the expansion parameter Θ is explicitly kept in all expressions, it can be simply set to
zero to obtain results for the Kundt class. Usefulness of these general results obtained
for all non-twisting and shear-free geometries in any metric theory of gravitation are
demonstrated on specific vacuum solutions to the Einstein field equations.
