Tangent bundle embeddings of manifolds in Euclidean space
Mohammad GhomiGeorgia Institute of Technology, Atlanta, United States
For a given -dimensional manifold we study the problem of finding the smallest integer such that admits a smooth embedding in the Euclidean space without intersecting tangent spaces. We use the Poincaré--Hopf index theorem to prove that , and construct explicit examples to show that , where denotes the -sphere. Finally, for any closed manifold , we show that .
