Rooted Weyl Alternants for the Graceful Tree Conjecture
Global alternants, extremal-edge flows, and exact pruning tests
An exact signed-enumeration framework for graceful tree labelings, with global alternants, directed edge classes, and two leaf recurrences. The reconstructed finite audit reproduces 7,812 rooted types and the pruning results through thirteen vertices.

What is this paper trying to establish?
Can graceful tree labelings be detected and pruned through exact signed alternants?
The central idea.
An exact signed-enumeration framework for graceful tree labelings, with global alternants, directed edge classes, and two leaf recurrences. The reconstructed finite audit reproduces 7,812 rooted types and the pruning results through thirteen vertices.
Method and partial progress; the universal Graceful Tree Conjecture is not resolved.
This manuscript develops a method and finite evidence, but it does not resolve the full open problem. The unresolved boundary is part of the published result.
What changes if the method holds?
The framework turns parts of the graceful-labeling search into auditable algebraic certificates and exact finite pruning tests, while keeping the universal conjecture explicitly open.
Where scrutiny should concentrate.
The paper identifies the following points as the highest-value targets for independent review.
- 01Orientation and inherited ordering conventions in the global and rooted identities.
- 02Validity of sibling-orbit reductions for every coefficient, not just endpoint counts.
- 03The distinction between finite nonvanishing certificates and a universal graceful-tree proof.
An open, inspectable research artifact.
The public record links the manuscript to its release, source package, review materials, and persistent identifier. Status travels with the paper; a reserved DOI is not presented as a published Zenodo record.
