Finite Smith–Toda complexes at every height

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

For every n ≥ 0, constructs a finite Smith–Toda spectrum at a prime p depending on n, with Brown–Peterson homology \(BP_*/(p,v_1,\ldots,v_n)\) and the canonical comodule structure. Thus Smith–Toda complexes exist at every height when the prime may vary; an explicit example realizes \(V(4)\) at p = 1009.

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 Finite Smith–Toda Complexes at Varying Primes, 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.

For every integer n\geq0, there exist a prime p and a finite p-local spectrum X such that

\BP_*X\cong\BP_*/(p,v_1,\ldots,v_n)

as graded \BP_*\BP-comodules, with the canonical quotient coaction and generator in degree zero.

Theorem 1.1

In A finite Smith–Toda complex V(4) at the prime 1009, 23 September 2026

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

At p=1009 there is a finite p-local spectrum X and an isomorphism

BP_*X\ \cong\ BP_*/(p,v_1,v_2,v_3,v_4)

of graded BP_*BP-comodules, with the canonical quotient comodule on the right and its generator in degree zero.

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.

Finite Smith–Toda Complexes at Varying Primes

23 September 2026, current edition.

Read it herePDF

For every nonnegative integer n, we construct a Smith–Toda complex \(V(n)\) at some prime p depending on n. It is a finite p-local spectrum whose Brown–Peterson homology is \(\mathrm{BP}_*/(p,v_1,\ldots,v_n)\) with its canonical comodule structure and generator in degree zero. Each listed generator is killed to its first power.

A finite Smith–Toda complex V(4) at the prime 1009

23 September 2026, current edition.

Read it herePDF

We construct a Smith–Toda complex \(V(4)\) at the prime 1009. It is an ordinary finite 1009-local spectrum whose Brown–Peterson homology is \(BP_*/(1009,v_1,v_2,v_3,v_4)\), with its canonical comodule structure and generator in degree zero.

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.
