Obtaining a class of Type O pure radiation metrics with a cosmological constant, using invariant operators

S. Brian Edgar, M. P. Machado Ramos

Using the generalised invariant formalism we derive a class of conformally flat spacetimes whose Ricci tensor has a pure radiation and a Ricci scalar component. The method used is…

Obtaining a class of Type N pure radiation metrics using invariant operators

M. P. Machado Ramos, S. Brian Edgar

We develop further the integration procedure in the generalised invariant formalism, and demonstrate its efficiency by obtaining a class of Petrov type N pure radiation metrics wit…
