A note on -gerbes and transgressions

    Università degli Studi di Verona, Italy


In this note we provide an explicit interpretation of a class of -gerbes with multi-layered connections in terms of transgression of a fibrewise closed -form on a fibration to a closed -form on the base manifold, with the basic example of the Euler class of an oriented vector bundle in mind (). Picken's and Ferreira–Gothen’s -gerbopoles are discussed from this point of view. Furthermore, string structures (à la Cocquereaux–Pilch and à la Spera–Wurzbacher) are briefly addressed and recast within the proposed framework.
