Regarding the parallelizability of the Milnor's seven dimensional exotic spheres: Parallelizability of the Milnor's exotic spheres in dimension 7 The following question naturally arises: Suppose that a manifold has some exotic structures,and is parallelizable with respect to one of them ,is that manifold also parallelizable with respect to other smooth structures?
