The Hilbert space L2(S1) We now focus on the class of functions with which Fourier series are most naturally associated. This is the set of “square-summable functions on the circle”, or L2(S1). Let’s start with S1: this is a circle that has circumference 1, which we can also think of as the interval [0,1] with the endpoints identiﬁed to a single point. the gray home

WebA Hilbert space is a vector space with an inner product such that the norm defined by turns into a complete metric space. If the metric defined by the norm is not complete , then is instead known as an inner product space . Examples of finite -dimensional Hilbert spaces include 1.

A Hilbert space H is said to be separable if H contains a countable dense subset {hn}. In this case, for every x in H and every 0 there exists an integer N and scalars {an}such that x n 1 N a nhn H for N N If H is a separable Hilbert space, then the Gram-Schmidt ...

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.
