Hilbert's space
WebDefinition 12.7. A Hilbert space is an inner product space (H,h·,·i) such that the induced Hilbertian norm is complete. Example 12.8. Let (X,M,µ) be a measure space then H:= L2(X,M,µ) with inner product (f,g)= Z X f· gdµ¯ is a Hilbert space. In Exercise 12.6 you will show every Hilbert space His “equiv-alent” to a Hilbert space of ... WebHilbert space is a vector space H over C that is equipped with a complete inner product. Let’s take a moment to understand what this means; much of it will be familiar from IB …

WebFeb 16, 2024 · Hilbert Space The functional is defined as a function whose range is in $\mathbb{R}$. Therefore, the functional space means the space whose elements are functions with codomain of real values space. However, it is difficult to imagine how each entry of the functional space consists of unlike the vector space. http://www-stat.wharton.upenn.edu/~stine/stat910/lectures/16_hilbert.pdf
Formally, a Hilbert space is a vector space equipped with an inner product that defines a distance function for which the space is a complete metric space. The earliest Hilbert spaces were studied from this point of view in the first decade of the 20th century by David Hilbert , Erhard Schmidt , and Frigyes Riesz . See more In mathematics, Hilbert spaces (named after David Hilbert) allow generalizing the methods of linear algebra and calculus from (finite-dimensional) Euclidean vector spaces to spaces that may be infinite-dimensional. … See more Lebesgue spaces Lebesgue spaces are function spaces associated to measure spaces (X, M, μ), where X is a set, M is a σ-algebra of subsets of X, and μ is a countably additive measure on M.
