摘要
In this note we provide an explicit interpretation of a class of (q - 1)-gerbes with multi-layered connections in terms of transgression of a fibrewise closed q-form on a fibration to a closed (q + 1)- form on the base manifold, with the basic example of the Euler class of an oriented vector bundle in mind (q >= 0). Picken's and Ferreira-Gothen's n-gerbopoles are discussed from this point of view. Furthermore, string structures (a la Cocquereaux-Pilch and a la Spera-Wurzbacher) are briefly addressed and recast within the proposed framework.
