WebC of complex numbers. A Hilbert space a special kind of vector space. This article starts with the general idea of a vector space over C and then walks through a series of specializations to arrive at the idea of a Hilbert space.1 Quantum theory uses only separable Hilbert spaces, which satisfy an extra condition that is closely WebHilbert space and bounded linear operators This chapter is mainly based on the rst two chapters of the book [Amr]. Its content is quite standard and this theory can be seen as a special instance of bounded linear operators on more general Banach spaces. 1.1 Hilbert space De nition 1.1.1.

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 WebGilbert Helmberg, Introduction to Spectral Theory in Hilbert Space (North-Holland, Amsterdam 1969; corr. 2nd pr. 1975; repr.
