Virasoro constraints for complete intersections and projective-bundle towers

OpenAI groups related papers into a “family”. OpenAI’s catalogue describes this one:

Proves the full ordinary unreduced descendant Virasoro conjecture for smooth complete intersections in complex projective space, in every genus and curve class with arbitrary cohomology insertions. The constraints also pass from any smooth projective complex base satisfying them to the projectivization of every algebraic vector bundle of rank at least two, and hence to projective-bundle towers.

The release has no Lean statement for this family, so there is no formal statement to compare with the result described above.

What the papers state

Theorem 1.1

In Virasoro Constraints for Projective Complete Intersections

Possible match to OpenAI’s description, selected from the papers’ main statements because it shares the most wording. No review confirming the selection is recorded.

Let X\subset\PP^N_\C be a smooth complete intersection. Its ordinary, unreduced total descendant potential satisfies the Virasoro constraints in every genus and curve class, with arbitrary insertions from H^*(X;\C).

Theorem 1.1

In Virasoro Constraints under Projectivization, 5 October 2026

The paper’s main theorem is shown as a possible match to OpenAI’s description. No review confirming the selection is recorded.

Let B be a smooth connected projective variety over \C, and let E be an algebraic vector bundle of rank r\geq2 on B. Let X=\mathbb P_B(E) parametrize one-dimensional subspaces of the fibers of E. Then

\V(B)\ \Longrightarrow\ \V(X).

The release does not say which paper theorem its catalogue describes. Both statements above are shown whole, the closer match to the description’s wording first. The atlas has not reviewed either choice.

Virasoro Constraints under Projectivization

5 October 2026, current edition.

Read it herePDF

We prove that full ordinary descendant Virasoro constraints pass from a smooth projective complex base to the projectivization of any algebraic vector bundle of rank at least two. The bundle need not split and satisfies no positivity requirement. Assuming the full constraints on the base, the conclusion includes every genus, each individual integral curve class, and all cohomology insertions, including primitive and odd classes. The result also applies successively to towers of projective bundles.

Virasoro Constraints for Projective Complete Intersections

Undated, current edition.

Read it herePDF

We prove the Virasoro conjecture for the ordinary descendant Gromov–Witten theory of smooth complete intersections in projective space, in every genus and curve class and with arbitrary cohomology insertions. This includes primitive and odd cohomology classes, with no semisimplicity assumption.

Independent comparisons and proof-verification reports

Does the Lean express the advertised result?

The release contains no Lean statement for this family, so there is no formal statement to compare with OpenAI’s description.
