WebJun 5, 2024 · A Hilbert space is a natural extension of the ordinary three-dimensional space in Euclidean geometry, and many geometric concepts have their interpretation in a Hilbert … Web1. Hilbert spaces We shall consider a class of real or complex vector spaces where the notion of a self-adjoint operator makes sense. This class includes all Euclidean spaces Rn, their complex analogues Cnand the classical Hilbert spaceH, which is in・]ite-dimensional complex space. All these spaces we call simply Hilbert spaces.

WebMay 17, 2013 · The Hilbert space H of the one-dimensional harmonic oscillator in the position representation is the set L 2 ( R) = L 2 ( R) / N (of equivalence classes) of square integrable functions ψ: R → C on the real line. The equivalence relation is modulo measurable functions that vanish a.e.

Some results about g-bases are proved. In particular, we characterize the g-bases and g-orthonormal bases. And the dual g-bases are also discussed.
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.
