Hilbert spaces arise naturally and frequently in mathematics and physics, typically as function spaces. 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. 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. Let L (X, μ) be the space of those complex … See more Pythagorean identity Two vectors u and v in a Hilbert space H are orthogonal when ⟨u, v⟩ = 0. The notation for this is u … See more Bounded operators The continuous linear operators A : H1 → H2 from a Hilbert space H1 to a second Hilbert space H2 are 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. In particular, the idea of an abstract linear space (vector space) had gained some traction towards the end of the 19th century: … 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 WebReview of Hilbert complexes In this section, we quickly review the abstract framework of Hilbert complexes, which forms the heart of the analysis in Arnold, Falk, and Winther [3] for mixed nite element methods. Just as the space of L2 functions is a prototypical example of a Hilbert space, the prototypical example of a Hilbert complex to keep ...

WebThis report aims to review some progress on discretizing Hilbert complexes. The emphasis is mainly on conforming nite elements on simplices, while other important topics are not covered, e.g., polyhedral elements, virtual elements, isogeometric analysis, nonconforming elements and applications. 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 …
