This paper contains corrections to Madea, Rosenberg, Torres-Ardila, "The Geometry of Loop Spaces II: Characteristic Classes, " Advances in Math. (287), 2016, 485-518. The main change is that results about ₁ (Diff (M) ) are replaced by results about ₁ (Isom (M) ), where Diff (M), Isom (M) refer to the diffeomorphism and isometry group of the manifold M.
Maeda et al. (Wed,) studied this question.
