Theorem hilhhi

Description: Deduce the structure of Hilbert space from its components. (Contributed by NM, 10-Apr-2008) (New usage is discouraged.)

Ref Expression
Hypotheses hilhh.1 ⊢ ℋ = BaseSet ⁡ U
hilhh.2 ⊢ + ℎ = + v ⁡ U
hilhh.3 ⊢ ⋅ ℎ = ⋅ 𝑠OLD ⁡ U
hilhh.5 ⊢ ⋅ ih = ⋅ 𝑖OLD ⁡ U
hilhh.9 ⊢ U ∈ NrmCVec
Assertion hilhhi ⊢ U = + ℎ ⋅ ℎ norm ℎ
