Talk:Functional Analysis/Hilbert spaces

There is no definition of a Hilbert space. In a proof, it makes sure an inner product space is complete before declaring it a Hilbert space but this is not enough. I see the chapter has been "almost done" since June 2008. Please, someone finish it off. Cpbm727 (discuss • contribs) 09:38, 13 March 2011 (UTC)
