Mathematical Properties of a Class of Four-dimensional Neutral Signature Metrics
D. Brooks, N. Musoke, D. McNutt +1
While the Lorenzian and Riemanian metrics for which all polynomial scalar curvature invariants vanish (the VSI property) are well-studied, less is known about the four-dimensional…

Killing vectors in higher dimensional spacetimes with constant scalar curvature invariants
David McNutt, Nicos Pelavas, Alan Coley
We study the existence of a non-spacelike isometry, ζ, in higher dimensional Kundt spacetimes with constant scalar curvature invariants (CSI). We present the particular forms for t…

CCNV Space-Times as Potential Supergravity Solutions
A. Coley, D. McNutt, N. Pelavas
It is of interest to study supergravity solutions preserving a non-minimal fraction of supersymmetries. A necessary condition for supersymmetry to be preserved is that the spacetim…
