Description

---What is the conjecture---

-Ω-Closure Conjecture (Canonical Fixed-Point Characterization of Algebraic Cycles)

-Let be a smooth projective variety over a number field, and let denote the space of rational Hodge classes. There exists a canonical -linear endomorphism.

\mathcal{H}_\Omega : H^{k,k}(X,\mathbb{Q}) \to H^{k,k}(X,\mathbb{Q})

-Equivalently, a rational Hodge class is algebraic if and only if it is fixed under the Ω-transport flow.

-This conjecture provides a structural fixed-point formulation of algebraicity that is independent of the classical Chow–Künneth projectors and is motivated by computational and variational evidence.

--Prerequisites needed---

-To formalize this conjecture, the following components would be required:

-1. Formalization of rational Hodge structures and the -component of cohomology for smooth projective varieties.
-2. A formal definition of an energy-minimizing endomorphism on a rational cohomology space (Ω-transport), abstracted as a self-adjoint linear operator.
-3. Fixed-point and kernel characterizations of self-adjoint operators on finite-dimensional inner-product spaces.
-4. Basic infrastructure for algebraic cycle classes and their realization in cohomology.
No advanced motivic machinery is required for the conjectural statement itself; it is expressible at the level of linear operators and fixed-point subspaces.

[ ] I plan on adding this conjecture to the repository

[x] This issue is up for grabs: I would like to see this conjecture added by somebody else

Research direction

Start by reviewing the attached formalization PDFs, especially “Proposed Content to Encode in Lean: Operators and Definitions” and “Core Equivalence Claim,” then compare them with the current Omega-Closure-Framework repository. No target files or tests are named; done would require adding a Lean formalization of the conjecture and its stated operator, fixed-point, and cycle-class components.
