“As particular cases of the type II spacetimes without pure radiation, Φ b 22 = 0 = Φ w 22 , we obtain the special electrovacuum solutions with gravitational waves that were found by García and Alvarez [35].”

“Pure type II gravitational waves in such type D electrovacuum spacetimes arise for H = f (u, ζ) + f (u, ζ), see [35,36,30,29].”

In the citing paper
“For α = β = C = 0, ε = 1, D = 2Λ, this is their special II-E (+) solution with Λ < 0 which can be written in the form (42) where ds 2 b is the Plebański-Hacyan metric (36).”

“For α = β = Λ, C = 0, ε = 1, D = 0 we obtain the (non-twisting subclass of) II-E (-) solution with Λ > 0 in the form (42) where ds 2 b is the other direct product Plebański-Hacyan metric of the form (36).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
