Exterior bundles in diffeology

Differential Geometry 2021-07-12 v2

Abstract

We explore several notions of kk-form at a point in a diffeological space, construct bundles of such kk-forms, and compare sections of these bundles to differential forms. As they are defined locally, our kk-forms can contain more information than the values of differential forms contain, and we illustrate this with many examples. To organize our work, we develop the basic theory of diffeological vector pseudo-bundles, including a detailed understanding of their limits and colimits, as well as a variety of fibrewise operations such as products, direct sums, tensor products, exterior powers and dual bundles.
