Cyclic length and chromatic fixed-point loss

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

Determines the optimal chromatic loss from geometric H-fixed points to geometric G-fixed points for every subgroup H of a finite p-group G. At every nonnegative height, the loss equals the shortest subnormal-chain length from H to G with cyclic quotients. Each quotient counts once regardless of order, and finite spectra witness sharpness.

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

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.

For every prime p, finite p-group G, subgroup H\le G, and integer n\ge0,

\boxed{r_n(G,H)=\ell(G,H).}

Cyclic length and chromatic fixed-point loss

24 September 2026, current edition.

Read it herePDF

For a finite p-group G and a subgroup H, we prove that the optimal chromatic fixed-point loss equals the shortest length of a subnormal chain from H to G with cyclic quotients. The equality holds at every prime and every nonnegative height, resolving positively the equality proposed by Kuhn and Lloyd.
