Project

Curvature invariants and classification of curvature tensors (KJB1019403)

In our previous work, we have determined all 4-dimensional Lorentzian manifolds with vanishing curvature invariants. Many of these spacetimes are exact solutions to string theory and have thus potential physical importance. We would...
