In a series of papers published in the course of his dissertation work in the mid 1950's, Andrzej Trautman drew upon the slow motion approximation developed by his advisor Infeld, the general covariance based strong conservation laws enunciated by Be

Algebraically special gravitational fields are described using algebraic and differential invariants of the Weyl tensor. A type III invariant is also given and calculated for Robinson-Trautman spaces.

A differential invariant is found for null fields of arbitrary spin. For null gravitational fields, the invariant is identified as that of Bicac and Pravda; its derivation from the Bel-Robinson tensor is given; and a simple expression is found for it

A new derivation is given of the Vahlen (1902) form of the local conformal transformations of Cn, v ■ (av+b)(cv+d)−1, where v∈Cn and a, b, c, d are suitable elements of the complex Clifford algebra Cl(n). The derivation is based on the homomorp

With any shear-free congruence of null geodesics in a Lorentzian geometry there is associated a Cauchy-Riemann three-space; and in certain spacetimes including the Ricci-flat spacetimes with expanding null shear-free (n.s.f.) congruences the deviatio
