Definition df-hba 27954
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 27984). Note that 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 28152. (Contributed by NM, 31-May-2008.) (New usage is discouraged.)
