The Solomon–Yau least-volume conjecture

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

Proves the Solomon–Yau least-volume conjecture for minimal hypersurfaces of round spheres. For every m ≥ 2, a closed connected minimal immersion into the unit sphere \(S^{m+1}\) with non-totally-geodesic image has volume at least that of the smallest minimal Clifford product, counting covering multiplicity.

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

The paper states

Theorem 1.1

In The Solomon–Yau least-volume theorem, 23 September 2026

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 m\ge2, let M^m be a closed connected smooth manifold, and let F:M\to S^{m+1} be a smooth minimal immersion into the unit round sphere. If F(M) is not totally geodesic, then

\Vol\bigl(M,F^*g_{\mathrm{round}}\bigr)\ge a_m.

The Solomon–Yau least-volume theorem

23 September 2026, current edition.

Read it herePDF

We prove the Solomon–Yau least-volume conjecture for minimal hypersurfaces of unit round spheres: in every dimension m ≥ 2, a closed connected minimal immersion with non-totally-geodesic image has volume at least the smallest m-dimensional minimal Clifford product. Volume is measured on the domain, so covering multiplicities are included.

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.
