Chromatic homotopy theory
In mathematics, chromatic homotopy theory is a subfield of
.Chromatic convergence theorem
In algebraic topology, the chromatic convergence theorem states the
Statement
Let denotes the Bousfield localization with respect to the Morava E-theory and let be a finite, -local spectrum. Then there is a tower associated to the localizations
called the chromatic tower, such that its homotopy limit is homotopic to the original spectrum .
The stages in the tower above are often simplifications of the original spectrum. For example, is the rational localization and is the localization with respect to p-local K-theory.
Stable homotopy groups
In particular, if the -local spectrum is the stable -local sphere spectrum , then the homotopy limit of this sequence is the original -local sphere spectrum. This is a key observation for studying stable homotopy groups of spheres using chromatic homotopy theory.
