Definition df-hba

Description: Define base set of Hilbert space, for use if we want to develop Hilbert space independently from the axioms (see comments in ax-hilex ). Note that ~H is considered a primitive in the Hilbert space axioms below, and we don't use this definition outside of this section. This definition can be proved independently from those axioms as Theorem hhba . (Contributed by NM, 31-May-2008) (New usage is discouraged.)
