1. Introduction. A contact form on an odd-dimensional manifold M of
dimension 2n + 1 is a 1-form 2 such that the (2n + 1)-form fl, given by
defines a volume form on M. We observe that any manifold admitting a contact
form is necessarily orientable and that a contact form defines a natural
Assume now that (M, 2) is a manifold together with a given contact form.
First of all, we note that 2 defines a 2n-dimensional vector bundle over M.
Indeed, consider M, where is given by
