Claims other papers make about this one
Each is checked against this paper’s own text: does it say what the citing paper says it does?
Ref.[37] gives the numerical value of C_0 as 0.833, but the paper also contains an analytic formula.
“In particular, Ref.[37] gives it as 0.833, but the paper also contains an analytic formula, found as a special case of”
From On Quantum Creation of a Toroidal Universe (2026) · cites this paper as [37]
The passages from “No smooth beginning for spacetime” (page unavailable) give analytic expressions for cosmological amplitudes and perturbations, but none identifies a quantity C₀ or gives it the value 0.833. Searches for “0.833,” “C_0,” and an analytic expression for that coefficient found no passage addressing the claim. (LLM, conf=0.75)

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.
