Submanifold - Wikipedi

  1. An immersed submanifold of a manifold M is the image S of an immersion map f: N → M; in general this image will not be a submanifold as a subset, and an immersion map need not even be injective (one-to-one) - it can have self-intersections. More narrowly, one can require that the map f: N → M be an injection (one-to-one), in which we call it an injective immersion, and define an immersed.

Immersions, submersions and critical values De nition 0.2 (Submersion and Immersion) If f: X!Y is smooth, then 1. If T pfis onto for all p2X, then fis called a submersion 2. If T pfis one-to-one for all p2X, then fis called a immersion 3. If fis an immersion and fis one-to-one, then f(X) is an immersed submanifold Claim: an immersed submanifold is not an embedded submanifold if and only if its manifold topology does not agree with the subspace topology.. Why I suspect the claim is true: the inclusion map is always injective by definition.Also, since it is a restriction of the identity, its derivative everywhere is just the identity transformation, and thus clearly injective

The geometry of immersed manifolds is a generalization of the classical differential geometry of surfaces in the Euclidean space $ \mathbf R ^ {3} $. The intrinsic and extrinsic geometries of an immersed manifold are usually described locally by means of the first and the second fundamental form, respectively. For immersions of an $ m $- dimensional manifold $ M ^ {m} $ in a manifold $ N ^ {n. Математика: погружённое подмногообрази Next, we introduce a more general kind of submanifolds, called immersed submanifolds, which turn out to be the images of injective immersions. At the end of the chapter, we show how the theory of submanifolds can be generalized to the case of submanifolds with boundary

Under suitable hypothesis, we are able to prove that such a spacelike submanifold is immersed into a slice of the ambient space. For this, we use three main core concepts: the well known generalized maximum principle of Omori and Yau, stochastic completeness and another appropriate maximum principle at infinity due to Yau. We also construct a nontrivial example of weakly trapped submanifold in.

An immersed submanifold M in a Riemannian manifold N is said to be properly immersed if the immersion is a proper map. K. Akutagawa and the author gave an affirmative partial answer to Conjecture 1 (Conjecture 2 particularly) as follows (cf. [2], [23]): Theorem 1.1 ([2]). Any biharmonic properly immersed submanifold in En is min-imal. For Conjecture 3, we consider a biharmonic properly. мат. погружённое подмногообрази Submanifold Last updated February 25, 2019 Immersed manifold straight line with self-intersections.

Kaehler submanifold immersed in M (i.e., complex submanifold with the induced Kaehler structure). Let J (resp. J) be the complex structure of M (resp.

So the immersed submanifold ##N## certainly is a manifold in its own sense, but ##i## might not be an embedding, thus the topology of ##N## and the subspace topology of ##i(N)## might have nothing to do with eachother. I don't think you should see an immersed submanifold as a subset of the manifold. A better way to see it is as a manifold such that an immersion to the big manifold exists. This.

On the other hand, there is another notion { a \di eological sub- manifold { that I nd useful. A di eological submanifold of M. The top diagram is incorrect - an immersed submanifold is the image of an injective immersion, and hence cannot have self-intersections. --18.87.1.187 19:23, 11 September 2007 It's true that the image is in conflict with the definition given.

Let be an immersed submanifold of an almost para-Hermitian manifold and a differentiable distribution on . We denote the orthogonal distribution to on by . Then, for all , we write where and are orthogonal projections on and , respectively. Next, we will give a sufficient and necessary condition for a distribution to be slant. Theorem 7. Let be a submanifold of an almost para-Hermitian. We prove that a compact, immersed, submanifold of C^n, lagrangian for a Kahler form, is rationally convex, generalizing a theorem of Duval and Sibony for embedded submanifolds Note that if X is a compact submanifold of X, then f(X) is in fact a compact smooth submanifold of N (since fj X: X !N is an embedding), and f is a di eo-morphism from Xonto f(X). In the example above, the bad thing is that the image f(X) of Xis not a smooth submanifold of T2 (but only an immersed submanifold) angles, a compact submanifold M of real dimension 2n, immersed into a Ka¨hler-Einstein mani-fold N of complex dimension 2n, must be either a complex or a Lagrangian submanifold of N, or have constant Ka¨hler angle, depending on n = 1, n = 2, or n ≥ 3, and the sign of the scalar curvature of N. These results generalize to non-minimal submanifolds some known results for minimal submanifolds.

I will describe the area functional for immersed sub-manifolds in a sub-Riemannian structure. Since we are interested in high codimensional submanifolds, the notion of degree introduced by Magnani and Vittone is a central tool in this setting. We will see that the area functional depends on the degree of the immersed submanifold. Then, it turns out that not all the possible variations are.

Let i : N ,→ M be a connected submanifold that is an integral curve for L, 3 so N is 1-dimensional. We assume i(N) meets N m 0 and we seek to prove that i factors (necessarily uniquely) through a C∞ map from N to N m 0. The preimage i−1(N m 0) is closed and non-empty in the connected manifold N, so to prove it equals N it suffices to prove openness. This is a local problem near each.
