Hopkins' algebraic chromatic splitting conjecture
Hopkins' algebraic chromatic splitting conjecture
Let be the coefficient ring of Morava -theory at height , let be its cooperations, and let denote the usual periodicity elements. For , consider the inverse systems of -comodules and their derived limits. Let be the unit map and let be the class constructed from the determinant fiber sequence. Hopkins' algebraic chromatic splitting conjecture. For all heights and sufficiently large primes , there are isomorphisms of -comodules
Moreover, these isomorphisms should be topologically realized by and , respectively. This algebraic form predicts the two nonzero derived-limit contributions corresponding to the unit and the degree class in the -local sphere. It is motivated by height-two computations and is recorded in the cited literature; the source presents it as a conjecture and does not state that it has been resolved in the stated generality.
