WebThe unit tangent bundle of the 2-sphere is parallelisable. In fact, every orientable 3-manifold is parallelisable. The latter can be proven by Computing . Nov 5, 2014 at 16:11 The unit tangent bundle of a sphere is usually just called a Stiefel manifold (of 2-frames). Nov 5, 2014 at 17:39 Show 9 more comments 1 Answer Sorted by: 12 W.Sutherland.

Weblower-dimensional spheres are constructed analogously to above. There one has the isomorphisms S1 ≈ U1 and S3 ≈ SO(3), which leaves S7 as the only non-group example. Global parallelizability of a manifold M(in the following referred to as just “parallelizability”) Webis always divisible by (2k — 1)!. I wonder if you have noted the connection of this result with classical problems, such as the existence of division algebras, and the parallelizability of spheres. According to Wu the Pontrjagin classes of any GLOT-bundle, reduced modulo 4, are determined by the Stiefel-Whitney classes of the bundle. (See On the Pontrjagin … irf7507trpbf
