- Title
Petrov type I spacetime curvature: Principal null vector spanning dimension.
- Authors
Bini, Donato; Geralico, Andrea; Jantzen, Robert T.
- Abstract
The class of Petrov type I curvature tensors is further divided into those for which the span of the set of distinct principal null directions has dimension 4 (maximally spanning type I) or dimension 3 (nonmaximally spanning type I). Explicit examples are provided for both vacuum and nonvacuum spacetimes.
