Geometrically, the chromatic filtration on the stable homotopy category can be interpreted as the decomposition of the category of quasicoherent sheaves on the moduli stack of 1-dimensional, commutative formal group laws in terms of the height filtration. The purpose of this talk to propose an alternative geometric model for the chromatic filtration, in terms of the Harder-Narasimhan stratification on a moduli stack of vector bundles on the Fargues-Fontaine curve. Warning: portions of this talk will be speculative.
