Zeldovich and Starobinsky state that for massless conformally coupled fields in a toroidal universe described by the metric (57) with the stated identifications, the Casimir contribution to the energy-momentum tensor has the form T^(C)μν = -(C/a^4) diag(1, -1/3, -1/3, -1/3).
“Zeldovich and Starobinsky (ZS), citing Refs.[12,[35][36][37][38], state that for massless conformally coupled fields in a toroidal universe described by the metric (57) with the stated identifications, the Casimir contribution to the energymomentum tensor has the form”
From On Quantum Creation of a Toroidal Universe (2026) · cites this paper as [36]
The Introduction discusses a closed-universe model and Lorentzian path integrals, not Casimir energy in a toroidal universe. Searches for Zeldovich and Starobinsky, conformally coupled fields, and the stated energy-momentum tensor found no passage addressing the claim in our copy. (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.
