Canonical Equivalence of Complex and Lagrangian Quantizations

Definitions and mathematical statement

Shared notation.

$\mathbb N=\{1,2,\ldots\}$; the standard number fields have their usual meanings. All additional conventions are stated locally.

Definitions and conventions.

A quantizable compact symplectic manifold $(X,\omega)$ has a prequantum Hermitian line bundle with compatible connection. A compatible complex polarization gives a Hilbert space of appropriate holomorphic sections. A real polarization from a Lagrangian fibration gives states associated with its Bohr--Sommerfeld fibers, on which the restricted connection has nonzero parallel sections. An isomorphism is canonical only if it is naturally determined by the specified geometric data, rather than chosen from an arbitrary basis.

Target retained from the canonical source catalogue.

Catalogue wording retained for traceability.

Given a compact symplectic manifold equipped both with a compatible-complex-structure quantization and with a Lagrangian-fibration quantization, construct a canonical isomorphism between the resulting quantum Hilbert spaces.

Source scope and qualification.

The prequantum data, singular-fiber treatment and any half-form corrections must match. Equality of dimensions or existence of some vector-space isomorphism is weaker than the canonical comparison requested.

Short English statement

Construct a natural identification between the Hilbert spaces from complex and Lagrangian polarizations of the same symplectic manifold.

Research attempt

Model, date and investigated scope.

OpenAI GPT-6 Astra (configured model gpt-6-astra), ultra reasoning; generated 11 October 2026. Proved residual phase freedom in equivariant unitary comparisons with simple matching weights; no canonical geometric pairing is constructed.

Sources and literature check.

Read the supplied definition, catalogue wording, source qualifications and reference entries for 30004285. The historical source/context and inherited status are retained; no fresh literature or novelty certification is claimed. No external theorem is used without proof in this attempt; explicit model assumptions are distinguished from facts about the source model.

A symmetry-compatible phase ambiguity.

Suppose two proposed quantization Hilbert spaces each carry a circle action with the same distinct integer weights $0,\ldots,k$. Choose normalized weight vectors $e_j$ and $f_j$. Any circle-equivariant linear map $T$ must have $Te_j=c_jf_j$: comparing coefficients in $T(e^{ij\theta}e_j)=e^{i\theta A}Te_j$ forces every component of different weight to vanish. Unitarity imposes only $|c_j|=1$. Hence \[ T_{\boldsymbol\gamma}e_j=e^{i\gamma_j}f_j,\qquad (\gamma_0,\ldots,\gamma_k)\in\mathbb R^{k+1}, \] is an entire family of equally equivariant unitaries. Even for $k=0$, an overall phase remains.

Application to an attempted canonical comparison.

Matching dimensions or toric weight labels between holomorphic sections and Bohr--Sommerfeld states cannot choose these phases. Normalizing each state removes its norm freedom but leaves exactly the ambiguity above. A pairing constructed from the common prequantum connection and half-forms could potentially fix relative phases or provide a projective map; that is additional geometric construction, not a consequence of representation multiplicities.

Scope audit.

The weight-space hypothesis is a restricted diagnostic and is not asserted for every compact symplectic manifold. Singular real-polarization fibers can also affect the existence and dimensions of the spaces. The first gap is a geometrically defined pairing with proved nondegeneracy and the claimed naturality for the actual matched prequantum and half-form data. This argument identifies a failure of an insufficient method, not nonexistence of a canonical isomorphism under richer data.

Verification and adversarial audit.

Checked the weight-intertwining equation, all independent unit phases and the one-dimensional boundary case; did not claim richer geometry cannot fix them. This is a GPT-6 Astra Ultra self-audit, not independent human verification. Prompt A drafting followed by prompt B scope/dependency/boundary self-audit. Checked the weight-intertwining equation, all independent unit phases and the one-dimensional boundary case; did not claim richer geometry cannot fix them. The remaining gap is: Construct and prove naturality/nondegeneracy of a polarization pairing using the full matched prequantum, singular-fiber and half-form data. Unresolved status and zero original-target completion are retained.

Coordinator checked the weight-space intertwining equation and its independent phase freedoms, without inferring nonexistence under additional geometric data. This additional check was model-assisted, not independent human verification.

Tools, process and contributions.

Python 3 and local file-reading/writing tools for manuscript serialization and structural checks; mathematical calculations were symbolic reasoning, with no numerical experiment or theorem prover. Contribution prompt A was followed by prompt B. GPT-6 Astra with ultra reasoning drafted the research and performed its stated self-audit; any additional coordinator contribution is identified in the verification and audit. A GPT-6-based Codex coordinator assembled the manuscript and checked repository integration; its exact variant and reasoning configuration were not exposed. No human mathematical contribution, independent human proof check or formal proof certification is supplied. Complete derivations and the consulted source references are included here; private reasoning transcripts are not published.

Final status and first remaining gap.

UNRESOLVED. Construct and prove naturality/nondegeneracy of a polarization pairing using the full matched prequantum, singular-fiber and half-form data.

Completion Estimate

COMPLETION: 0% The proved calculation is an elementary auxiliary result or a test of a restricted strategy; no new portion of the full source target is established.
