Hilbert inequality
In mathematics, especially functional analysis, Bessel's inequality is a statement about the coefficients of an element in a Hilbert space with respect to an orthonormal sequence. The inequality was derived by F.W. Bessel in 1828. Let be a Hilbert space, and suppose that is an orthonormal sequence in . Then, for any in one has where ⟨·,·⟩ denotes the inner product in the Hilbert space . If we define the infinite sum WebI will rst discuss the de nition of pre-Hilbert and Hilbert spaces and prove Cauchy’s inequality and the parallelogram law. This material can be found in all the lecture notes listed earlier and many other places so the discussion here will be kept succinct. Another nice source is the book of G.F. Simmons, \Introduction to
