Extract

Let X be a compact differentiable n-manifold of class C and let f be a C map of X into euclidean (n + k)-space. Then f is an immersion if its jacobian has rank n at each point of X. It is an embedding if it is also one-one. We write Xn + k to denote the existence of an immersion, Xn + k to denote the existence of an embedding. By a theorem of Whitney, we have X ⊆ 2n − 1, X ⊂ 2n.
