Just to expand on my comment, you'll need to apply the theorem that the continuous image of a compact space is compact. But, the problem is missing a hypothesis: you'll need to assume that the …

WitrynaOn page 86 of John Lee's Introduction to smooth manifolds there is an example of an injective immersion that is not a topological embedding: $\beta : (-\pi, \pi) \to … Witryna60. When topologists speak of an "immersion", they are quite deliberately describing something that is not necessarily an "embedding." But I cannot think of any use of …
WitrynaThen there exists an immersion g : M −→ R2n+1 which is a δ-approximation of f. Then there exists an injective immersion h : M −→ R2n+1 which is a δ-approximation of g with L (h) = ∅. Hence h is an embedding and h (M) is closed. 3 References [1] Milton Persson. The Whitney Embedding Theorem. Umea UniversityVT˙ 2014 [2] William M ... WitrynaA smooth embedding is an injective immersion f : M → N that is also a topological embedding, so that M is diffeomorphic to its image in N. An immersion is precisely a …
WitrynaNash–Kuiper theorem. Let (M, g) be an m-dimensional Riemannian manifold and f: M n a short smooth embedding (or immersion) into Euclidean space ℝ n, where n ≥ m + 1. … In general topology, an embedding is a homeomorphism onto its image. More explicitly, an injective continuous map between topological spaces and is a topological embedding if yields a homeomorphism between and (where carries the subspace topology inherited from ). Intuitively then, the embedding lets us treat as a subspace of . Every embedding is injective and continuous. Every map that is injective, continuous and either open or closed is an embedding; however there are al…

WitrynaThe base change of a closed immersion is a closed immersion. Proof. See Schemes, Lemma 26.18.2. $\square$ Lemma 29.2.5. A composition of closed immersions is a closed immersion. Proof. We have seen this in Schemes, Lemma 26.24.3, but here is another proof. Namely, it follows from the characterization (3) of closed immersions in … fix frayed clothesWitrynaembedding and immersion dimensions. Theorem 2.4, due to Eliashberg and Gromov [43] (1992) and Schu¨rmann [101] (1997), settles this question for Stein manifolds of dimension > 1.
