Algebraic classification of spacetimes using discriminating scalar curvature invariants
Alan Coley, Sigbjorn Hervik
The Weyl and Ricci tensors can be algebraically classified in a Lorentzian spacetime of arbitrary dimensions using alignment theory. Used in tandem with the boost weight decomposit…

Pseudo-Riemannian VSI spaces
Sigbjorn Hervik, Alan Coley
In this paper we consider pseudo-Riemannian spaces of arbitrary signature for which all of their polynomial curvature invariants vanish (VSI spaces). We discuss an algebraic classi…
