In previous papers, the author has constructed differential forms and Chen-Souriau cohomology groups on the Hölder loop space over a compact Riemannian manifold. In the present paper he considers the construction of such a diffeology over the rough loop space in the sense of the rough paths introduced in [T. J. Lyons
, Rev. Mat. Iberoam. 14, No. 2, 215–310 (1998; Zbl 0923.34056
)]. He shows that the cohomology groups constructed in this sense over the rough loop space are equal to the de Rham cohomology groups of the Hölder loop space. In particular, a line bundle over the rough loop space is isomorphic to a line bundle of the Hölder loop space. It is also shown that the transgression of a three form in the sense of Brylinski determines a continuous line bundle over the rough loop space.
