Higher Vector Bundles

Résumé fourni par la source

Abstract We introduce higher analogs for cleavages in the context of (Kan) simplicial fibrations. We apply them to obtain geometric models for representations up to homotopy of (higher) Lie groupoids. Concretely, we set an equivalence between representations up to homotopy and simplicial vector bundles endowed with a cleavage. Our result is an incarnation of the Higher Grothendieck Correspondence, it can be seen as a relative Dold–Kan Theorem and extends earlier work of Gracia-Saz and Mehta on VB-groupoids.
