WebBy Nash's embedding theorem, we can always embed the disc D real-analytically and isometrically into real Euclidean space R n for some large n. (I think n = 5 = 2 dim R D + 1 is sufficient.) I'm wondering whether we have a complex-analytic embeddeding of the disc D into complex Euclidean space.

WebRecall that the disc embedding theorem begins with smooth immersions and yields topological, flat embeddings. As usual, an immersion is a local embedding and every map from a surface to a smooth 4-manifold can be approximated by an immersion. That is, every such function is homotopic to an immersion, which can be chosen to be arbitrarily close ... WebTopological 4-manifolds: the disc embedding theorem and beyond Abstract: In 1982 Freedman proved the 4-dimensional Poincare conjecture in the topological category. The key tool in the proof was the disc embedding theorem, which allows a topological version of the Whitney trick in certain cases in dimension four.
