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?
For a spin-1/2 field with antiperiodic boundary conditions, C_{1/2} = 0.3914, so there is no cancellation.
“On the other hand, for a spin-1/2 field with antiperiodic boundary conditions, as studied in Ref. [39], ZS state that C 1/2 = 0.3914, so there is no cancellation.”
From On Quantum Creation of a Toroidal Universe (2026) · cites this paper as [39]
Section III (Scalar Matter; page unavailable) studies a scalar field, not a spin-1/2 field with antiperiodic boundary conditions. Searches for that field and boundary condition, cancellation, and 0.3914 found no passage in our copy addressing the attributed claim. (LLM, conf=0.76)

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.
