Theorem dochpolN 38068

Description: The subspace orthocomplement for the DVecH vector space is a polarity. (Contributed by NM, 27-Dec-2014.) (New usage is discouraged.)

**Hypotheses**
Ref	Expression
dochpol.h	⊢ 𝐻 = (LHyp‘𝐾)
dochpol.o	⊢ ⊥ = ((ocH‘𝐾)‘𝑊)
dochpol.u	⊢ 𝑈 = ((DVecH‘𝐾)‘𝑊)
dochpol.p	⊢ 𝑃 = (LPol‘𝑈)
dochpol.k	⊢ (𝜑 → (𝐾 ∈ HL ∧ 𝑊 ∈ 𝐻))

**Assertion**
Ref	Expression
dochpolN	⊢ (𝜑 → ⊥ ∈ 𝑃)

Proof of Theorem dochpolN Dummy variables 𝑥 𝑦 are mutually distinct and distinct from all other variables.
