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?

  • The first attempt [12] was largely exploratory, considered only the simplest loop states and eigenvalues, and made no claim of completeness.

    “The first attempt [12] was largely exploratory. Thus, although the key ideas were recognized, the very simplest of loop states were considered and the simplest eigenvalues were looked at; there was no claim of completeness.”

    From Quantum theory of geometry: I. Area operators (1997) · cites this paper as [12]

    Section 4, Theorem 1 (page unavailable), states that spin network states on embedded graphs span the full kinematical Hilbert space, rather than considering only the simplest loop states without a completeness claim. The paper does leave the construction of all diffeomorphism-invariant physical states open (Section 5), but that is a different qualification. The passages found do not report the claimed eigenvalue calculations. (LLM, conf=0.82)

    Checked by a reasoning model — may be wrong.

    Experimental — accuracy not yet measured
  • In the present language, the first attempt [12] corresponds to restricting to bi-valent graphs.

    “In the present language, this corresponds to restricting oneself to bi-valent graphs.”

    From Quantum theory of geometry: I. Area operators (1997) · cites this paper as [12]

    Section 4, “Spin Network States” (page unavailable), defines Baez’s spin network states on any embedded graph, not only bi-valent graphs. Section 5, “Conclusions” (page unavailable), describes a single-loop graph as a particular example; it does not make bi-valent graphs a restriction of the paper’s approach. (LLM, conf=0.79)

    Checked by a reasoning model — may be wrong.

    Experimental — accuracy not yet measured
  • The fundamental 1-dimensional excitations of geometry can be packed appropriately to provide a geometry which, when coarse-grained on scales much larger than the Planck length, leads to continuum geometries.

    “Just as a polymer, although intrinsically 1-dimensional, exhibits 3-dimensional properties in sufficiently complex and densely packed configurations, the fundamental 1-dimensional excitations of geometry can be packed appropriately to provide a geometry which, when coarse-grained on scales much larger than the Planck length, lead us to continuum geometries [12,22].”

    From Quantum theory of geometry: I. Area operators (1997) · cites this paper as [12]

    The Introduction (page unavailable) describes quantum-gravity spin-network states using graphs with labeled edges, supporting the claim’s graph-based aspect. Neither that passage nor the Conclusions (page unavailable) says that densely packed excitations yield continuum geometry when coarse-grained above the Planck scale. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • For bi-valent graphs, apart from an overall numerical factor, the present results reduce to those of [12].

    “In this case, apart from an overall numerical factor (which does, however, have some conceptual significance) our results reduce to that of [12].”

    From Quantum theory of geometry: I. Area operators (1997) · cites this paper as [12]

  • Area operators were first examined in the loop representation.

    “Area operators were first examined in the loop representation.”

    From Quantum theory of geometry: I. Area operators (1997) · cites this paper as [12]

    Section 3, “The Loop Representation,” describes the representation and its mathematical framework, but does not discuss area operators. Searches for “area operators first examined” and “area operator area surface geometric operators” found no passage addressing when or where area operators were first examined. The indexed passages provide no page numbers. (LLM, conf=0.72)

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.
