| 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    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 ,
, and before df-hnorm 8832 above. See
also the comment in ax-hilex 8864. |
