Hopkins's chromatic splitting conjecture
Work -locally. For each , consider the chromatic fracture square and the map . If is the -completion of a finite spectrum, let denote a prospective splitting of this map.
Chromatic splitting conjecture. If is the -completion of a finite spectrum, then a splitting exists for all .
The conjecture describes how the chromatic localizations assemble through the chromatic tower and is motivated by computations of Morava stabilizer group cohomology and the homotopy groups of . Its resolution is not given in the supplied source.

Claimed by OpenAI. Claims no homotopy retraction for the canonical weak chromatic-splitting map at height p for primes at least five and at height p+1 for primes at least seven, with nonzero sphere-product kernel classes.
Scope relative to this problem: The source claims no homotopy retraction for the canonical weak chromatic-splitting map at height p for primes p>=5 and height p+1 for primes p>=7, with nonzero sphere-product kernel classes. This is a negative instance of the universally quantified weak splitting assertion for the p-completed sphere, keeping the stated heights and prime bounds.
