Webrelevant de nition). The main theorem of Nash’s note is then the following. Theorem 1.1.1 (Existence of real algebraic structures). For any closed connected smooth n-dimensional manifold there is a smooth embedding v: !R2n+1 such that v() is a connected component of an n-dimensional algebraic subvariety of R2n+1. WebKodaira's theorem asserts that a compact complex manifold is projective algebraic if and only if it is a Hodge manifold.

"WebThis is formally described as the embedding of a manifold M, which is a smooth injection Ξ: M → R n to a Euclidean space so that we can understand the manifold as a subset Ξ (M) of R n (Fig. 6). Whitney embedding theorem (Persson, 2014; Whitney, 1944) shows that an m-dimensional manifold can always be embedded into R 2 m. " - Manifold embedding theorem
