Berend Schneider, Neev Khera
The asymptotic structure of space-time is studied by imposing conditions on the asymptotics of the metric. These conditions are weak enough to include large classes of physically r…

Newman-Penrose-like exact and approximate conservation laws: a covariant and conformal formulation
Berend Schneider
Using a conformal extension of the Geroch-Held-Penrose (GHP) formalism I derive a manifestly covariant and conformal expression of Newman-Penrose (NP) constants, which are a set of…
