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 ⊥ v. More generally, when S is a subset in H, the notation u ⊥ S means that u is orthogonal to every element from S. See more Motivating example: Euclidean vector space One of the most familiar examples of a Hilbert space is the See more Prior to the development of Hilbert spaces, other generalizations of Euclidean spaces were known to mathematicians and physicists. … See more Many of the applications of Hilbert spaces exploit the fact that Hilbert spaces support generalizations of simple geometric concepts like See more Bounded operators The continuous linear operators A : H1 → H2 from a Hilbert space H1 to a second Hilbert space H2 are bounded in the sense that they map See more WebMay 26, 2024 · Hilbert space is isomorphic to ` 2, the space of all square summable sequences. One of the main theorems related to Hilbert spaces is the Riesz Representation Theorem,
WebThe book presents an introduction to the geometry of Hilbert spaces and operator theory, targeting graduate and senior undergraduate students of mathematics. Major topics discussed in the book are inner product spaces, linear operators, spectral theory and special classes of operators, and Banach spaces. WebOct 7, 2024 · The central message is that the Hilbert space itself tells us almost nothing about a theory. The pattern of observables is what matters. Different ways of representing the Hilbert space may be more or less convenient for different patterns of observables, but the observables are what matters. Yes, there are many different fermionic field theories.

The name spectral theory was introduced by David Hilbert in his original formulation of Hilbert space theory, which was cast in terms of quadratic forms in infinitely many variables. The original spectral theorem was therefore conceived as a version of the theorem on principal axes of an ellipsoid, in an infinite-dimensional setting.
