Algebraic models of stable Postnikov invariants Johnson, Niles
Description
We describe algebraic data in a symmetric monoidal 2-category which correspond to the bottom two Postnikov invariants of its \(K\)-theory spectrum. Our applications include: an obstruction to strictification of the symmetric monoidal structure, a model for the \(2\)-type of the sphere, and the units-Picard-Brauer sequence of commutative ring spectra. This is work in progress, joint with Nick Gurski and Angélica Osorno.
