The pith
Graded Artinian Gorenstein algebras satisfy Parseval-Rayleigh identities over positive characteristic fields
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
We formulate and prove Parseval-Rayleigh identities for graded Artinian Gorenstein algebras over fields of positive characteristic. Specializing the general result, we provide an alternative proof of the Parseval-Rayleigh identities of generic Artinian reductions of Stanley-Reisner rings of oriented simplicial spheres.
What carries the argument
The graded Artinian Gorenstein algebra structure, whose socle and duality pairing support the formulation of the Parseval-Rayleigh identities.
Load-bearing premise
The algebras are graded Artinian Gorenstein over a field of positive characteristic and the specialization to generic Artinian reductions of Stanley-Reisner rings of oriented simplicial spheres preserves the duality and grading properties.
What would settle it
A concrete graded Artinian Gorenstein algebra over a positive characteristic field in which the formulated Parseval-Rayleigh identity fails to hold when both sides are computed explicitly.

Referee Report
Summary. The manuscript formulates and proves Parseval-Rayleigh identities for graded Artinian Gorenstein algebras over fields of positive characteristic. Specializing the general result, it provides an alternative proof of the Parseval-Rayleigh identities of generic Artinian reductions of Stanley-Reisner rings of oriented simplicial spheres.
Significance. If the central proofs are correct, the result is significant for extending Parseval-Rayleigh identities beyond characteristic zero into positive characteristic, where Gorenstein duality and socle pairings behave differently. The specialization supplies an alternative algebraic proof for a combinatorial setting (Stanley-Reisner rings of oriented spheres), strengthening links between commutative algebra and combinatorial topology. The work uses standard graded Gorenstein duality without introducing ad-hoc parameters or circular definitions.
minor comments (3)
- [§3] The proof of the general identity (likely in §3) would benefit from an explicit statement of the non-degeneracy condition on the pairing in positive characteristic, even if it follows from standard facts.
- [§4] In the specialization section, clarify how the generic Artinian reduction interacts with the orientation of the simplicial sphere to preserve the required grading and duality.
- [Introduction] A short remark comparing the new proof with existing ones (e.g., those using characteristic-zero techniques) would improve context in the introduction.
Simulated Author's Rebuttal
We thank the referee for their positive summary and recommendation of minor revision. No specific major comments were raised in the report, so we have no points to address point-by-point. We have performed a careful review of the manuscript for any minor issues such as typographical errors or clarifications and will incorporate those in the revised version.
Circularity Check
No significant circularity detected in derivation chain
full rationale
The paper formulates and proves Parseval-Rayleigh identities for graded Artinian Gorenstein algebras over positive-characteristic fields, then specializes the result to generic Artinian reductions of Stanley-Reisner rings of oriented simplicial spheres as an application. The central derivation relies on the standard non-degenerate pairing and socle duality properties of Gorenstein algebras, which are external to the identities being proved. No self-definitional reductions, fitted parameters renamed as predictions, or load-bearing self-citations that force the result by construction appear in the abstract or claim structure. The alternative proof is presented as building on prior literature without reducing the identities to quantities already defined in terms of themselves.
Axiom & Free-Parameter Ledger
axioms (2)
- domain assumption Graded Artinian Gorenstein algebras possess the expected socle duality and grading symmetry in positive characteristic.
- domain assumption Generic Artinian reductions of Stanley-Reisner rings of oriented simplicial spheres inherit the Gorenstein property and the relevant grading.
