WebThe definitions I read in Lee's Smooth Manifolds is: Embedded Submanifold: S ⊂ M is an embedded submanifold if S → M is an embedding. Immersed Submanifold: S ⊂ M is an immersed submanifold if S → M is an injective immersion. Thus, an immersed submanifold with the subspace topology is an embedded submanifold. WebF(M) ˆN is called an embedded smooth submanifold if F is an embedding. If F is the inclusion map : M ,!N, we will say that M ˆN is a smooth submanifold if the inclusion is an embedding. If M ˆN is a smooth submanifold, the number dim(N) dim(M) is called the codimension of M in N. David Lindemann DG lecture 5 5. May 20247/20

Given any immersed submanifold S of M, the tangent space to a point p in S can naturally be thought of as a linear subspace of the tangent space to p in M. This follows from the fact that the inclusion map is an immersion and provides an injection $${\displaystyle i_{\ast }:T_{p}S\to T_{p}M.}$$ Suppose S is an … See more In mathematics, a submanifold of a manifold M is a subset S which itself has the structure of a manifold, and for which the inclusion map S → M satisfies certain properties. There are different types of submanifolds … See more Smooth manifolds are sometimes defined as embedded submanifolds of real coordinate space R , for some n.

Embedding submanifold

WebIt is not suprising that a smooth submanifold (with the subspace topology) is always a smooth manifold by itself, and the inclusion map from the submanifold to the ambient manifold is always an embedding: Theorem 1.2. Let Sbe a k-dimensional submanifold of M. Then with the subspace topology, Sadmits a unique smooth structure so that WebFurthermore, when a parametric model (after a monotonic scaling) forms an affine submanifold, its natural and expectation parameters form biorthogonal coordinates, and such a submanifold is dually flat for α = ± 1, generalizing the results of Amari’s α-embedding. The present analysis illuminates two different types of duality in ...

WebAbstract manifolds have a canonical tangent bundle, but do not have a normal bundle: only an embedding (or immersion) of a manifold in another yields a normal bundle. However, since every manifold can be embedded in , by the Whitney embedding theorem, every manifold admits a normal bundle, given such an embedding. WebOct 7, 2024 · Nevertheless, it may still happen that the graph of y= f(x) is a smooth submanifold of R2, even though fis not smooth. Example 1.11. The graph of y= 3 p xis a smooth submanifold of R2. Proof. It is the graph of x= y3, which is smooth. Remark 1.12. We will see later that every smooth submanifold of R2 is locally either a graph
