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 See more Many of the applications of Hilbert spaces exploit the fact that Hilbert spaces support generalizations of simple geometric concepts like projection and change of basis from their usual finite dimensional setting. In particular, the spectral theory of continuous See more Motivating example: Euclidean vector space One of the most familiar examples of a Hilbert space is the Euclidean vector space consisting of three … See more Prior to the development of Hilbert spaces, other generalizations of Euclidean spaces were known to mathematicians and physicists.
