Separable space

Ein topologischer Raum heißt separabel, wenn es eine höchstens abzählbare Teilmenge gibt, die in diesem Raum dicht liegt. Kriterien für separable Räume [ Bearbeiten | Quelltext bearbeiten ] Besitzt ein topologischer Raum eine (höchstens) abzählbare Basis , so ist er separabel Separable Space. A topological space having a countable dense subset. An example is the Euclidean space with the Euclidean topology, since it has the rational lattice as a countable dense subset and it is easy to show that every open -ball contains a point whose coordinates are all rational. Barile, Margherita In mathematics, a topological space is called separable if it contains a countable, dense subset; that is, there exists a sequence { x n } n = 1 ∞ {\displaystyle \{x_{n}\}_{n=1}^{\infty }} of elements of the space such that every nonempty open subset of the space contains at least one element of th

A topological space (X, τ) is said to be a separable space if it has a countable dense subset in X; i.e., A ⊆ X, A ¯ = X, or A ∪ U ≠ ϕ, where U is an open set. In other words, a space X is said to be a separable space if there is a subset A of X such that (1) A is countable (2) A ¯ = X (A is dense in X) Lernen Sie die Übersetzung für 'separable space' in LEOs Englisch ⇔ Deutsch Wörterbuch.

1. When the state spaces are infinite-dimensional, density matrices are replaced by positive trace class operators with trace 1, and a state is separable if it can be approximated, in trace norm, by states of the above form. If there is only a single non-zero, then the state is called simply separable (or it is called a product state)
2. A metrizable space is separable if and only if it is second-countable. This means that the euclidean topology on R n has a countable basis. This countable basis is explicitely described in the first paragraph of the proof and is put to use in the second paragraph

7. As far as I know the word separable was introduced by M. Fréchet in Sur quelques points du calcul fonctionnel, Rend. Circ. Mat. Palermo 22 (1906), 1-74. The paper can be obtained via this link (Springer). It's the famous paper in which he introduced metric spaces. He considers first slightly more general objects which he calls classes (V): where (V) stands for voisinage — neighborhood

A finite product of separable spaces is separable. The countable dense subset that we take for the product is the Cartesian product of countable dense subsets for each. Hereditariness on open subsets. This property of topological spaces is hereditary on open subsets, or is open subspace-closed. In other words, any open subset of a topological space having this property, also has this property. Let H be an abstract, separable Hilbert space over the complexes, X a locally compact space and dν a measure on X. Let |x,i〉 be a family of vectors in H, defined for each x in X and i =1,2,3N, where N is usually a finite integer, although it could also be infinite. We assume that this set of vectors possesses the following properties: 1

1. In topology, a second-countable space (also called a completely separable space) is a topological space having a countable base. It is well known that a second-countable space is separable. For the proof consider a second-countable space X with countable basis B = { B n; n ∈ N }
2. In other words, $S$ is dense in $M$ if every open ball contains a point of $S$. We will now look at a special type of metric space known as a separable metric space.

A Hilbert space is called separable if it has a countable basis. The Gram-Schmidt orthonormalization proves that every separable Hilbert space has an orthonormal basis. We give several characterizations of an orthonormal basis involving the Fourier expansion, the completness relation, and the Parseval relation space is separable if it has a countable dense subset. Using the fact that any point in the closure of a set is the limit of a sequence in that set (yes?) it is easy to show that Q is dense in R,andsoR is separable. A discrete metric space is separable if and only if it is countable. My favourite example of a non-separable space is a hedgehog space of uncountable spinyness. One handy result is. 1 . Separable Preferences • Let I be a finite (for now) set of indices (e.g. time periods, fruits, states). (We will see a representation theorem for countably many time periods, it needs more assumptions. And the expected utility representations extend to uncountable state spaces, this also needs more structure Not signed in. Want to take part in these discussions? Sign in if you have an account, or apply for one belo It is usually not your images that are directly « linearly separable », they are the points that result from the features you extract from the images that are linearly separable. These features can be seen as a kernel applied to the raw images, that project the images into a space. In this last space, data point corresponding to images can be linearly separable and in that case a SVM with. A Hilbert space is separable in the strong topology if and only if it is separable in the weak topology; a convex set (in particular, a linear subspace) in a Hilbert space is strongly closed if and only if it is weakly closed. As in the theory of general Banach spaces, so, too, in the theory of Hilbert spaces, the concept of separability plays an important role. A Hilbert space is separable if.

Abstract. In this chapter we study separable Asplund spaces, i.e., Banach spaces with a separable dual space. These spaces admit many equivalent characterizations, in particular by means of C 1-smooth renormings and differentiability properties of convex functions.Asplund spaces also play an important role in applications A normed space is called separable if a fundamental sequence exists. Many infinite dimensional spaces are easily seen to be separable. For instance, the normed space of square integrable functions with the L 2 norm on the unit circle in the complex plane is separable, and its fundamental sequence consists of complex exponential functions, or, the Fourier series of the function.

separable spaces are weakly Lindelöf: given a countable dense subset and an open cover choose for each point of the subset an open from the cover. Lindelöf spaces are trivially also weakly Lindelöf. a space with a σ \sigma-locally finite base is first countable: obviously, every point is contained in at most countably many sets of a σ \sigma-locally finite base. a first-countable space is. We discuss, within the simplified context provided by the polymeric harmonic oscillator, a construction leading to a separable Hilbert space that preserves some of the most important features of the spectrum of the Hamiltonian operator. This construction may be applied to other polymer quantum mechanical systems, including those of loop quantum cosmology, and is likely generalizable to certain.

of non-separable commodity space, a similar result is also established if the space of agents is decomposed into countably many diﬀerent types. 1.

These often are really more of exercises in algebra than anything else. So the first separable differential equation is: dy over dx is equal to x squared over 1 minus y squared. And actually, this is a good time to just review our terminology. So. Then any infinite subset is dense, in particular the countable infinite ones, and so the space is separable. We show that the space is not first countable, which implies that it could also not be second countable. Suppose it is first countable and fix some , then this has a countable local base . Now . is a countable union of finite sets, and so is countable. Therefore there exists some which.  Separable space - en

Separability is an overlooked structure of SLA this result is not trivial: If X is a compact $T_2$ space $X$, then $C(X)$ is separable iff there is a metric $Xtimes Xrightarrow R$ that induces the topology of $X$ To describe infinitely many particles would require a non-separable Hilbert space, I believe. (You can still get a countable basis for an infinite number of particles if there is a vacuum state in which all particles have the lowest possible energy level. Then the infinite number of particles in their ground state can be eliminated through redefining the creation and annihilation operators.
