Hilbert space - Wikipedia
WebIn mathematics, Hilbert spaces (named after David Hilbert) allow the methods of linear algebra and calculus to be generalized from (finite-dimensional) Euclidean vector spaces to spaces that may be infinite-dimensional. Hilbert spaces arise naturally and frequently in mathematics and physics, typically as function spaces.
Hilbert Space -- from Wolfram MathWorld
WebA Hilbert space is a vector space H with an inner product <f,g> such that the norm defined by |f|=sqrt(<f,f>) turns H into a complete metric space. If the metric defined by the norm is not complete, then H is instead known as an inner product space.
Hilbert Space | Brilliant Math & Science Wiki
WebA Hilbert space is a vector space V V equipped with an inner product, which can be thought of as a generalization of the dot product in Euclidean space, with the additional property that the metric coming from the inner product makes V V into a complete metric space.

WebMay 25, 2024 · Hilbert space, in mathematics, an example of an infinite-dimensional space that had a major impact in analysis and topology. The German mathematician David Hilbert first described this space in his work on integral equations and Fourier series, which occupied his attention during the period 1902–12.

WebLecture 14: Basic Hilbert Space Theory. Description: Last time we discussed pre-Hilbert spaces (Hilbert spaces’ little brothers), and now we define Hilbert spaces (what pre-Hilbert spaces really want to be). With the notion of an inner product, we define analogous linear algebra tools for functional analysis.
