WebA Hilbert space is also a Banach space: Definition 8. A Banach space B is a normed space with associated metric = d(x,y) x&y such that every Cauchy sequence in B has a limit in B. The difference between a Banach space and a Hilbert space is the source of the norm. In the Hilbert space case the norm is defined via the inner product, whereas ... WebA Hilbert space is a complete, inner product space. Every Hilbert space is a Banach space but the reverse is not true in general. In a Hilbert space, we write f n!f to mean that jjf n fjj!0 as n!1. Note that jjf n fjj!0 does NOT imply that f n(x) !f(x). For this to be true, we need the space to be a reproducing kernel Hilbert space which we ...
