Theorem axhilex 8846
Description: Derive axiom ax-hilex 8864 from Hilbert space under ZF set theory.

Before introducing the 18 axioms for Hilbert space, we first prove them as the conclusions of theorems axhilex 8846 through axhcompl 8863, using ZFC set theory only. These show that if we are given a known, fixed Hilbert space U = <.<. +h , .h >., normh>. that satisfies their hypotheses, then we can derive the Hilbert space axioms as theorems of ZFC set theory. In practice, in order to use these theorems to convert the Hilbert Space explorer to a ZFC-only subtheory, we would also have to provide definitions for the 3 (otherwise primitive) class constants +h, .h, and .ih before df-hnorm 8832 above. See also the comment in ax-hilex 8864.
