DESCRIPTION:Daniel Fuentes-Keuthan\, Johns Hopkins University\nWe reconcep
 tualize the process of forming n-excisive approximations to ∞-categories
 \, in the sense of Heuts\, as inverting the suspension functor lifted to A
 n-cogroup objects. We characterize n-excisive ∞-categories as those ∞-
 categories in which An-cogroup objects admit desuspensions. Applying this 
 result to pointed spaces we reprove a theorem of Klein-Schwänzl-Vogt: eve
 ry 2-connected cogroup-like A∞-space admits a desuspension.
