Theorem hgmapffval 41887

Description: Map from the scalar division ring of the vector space to the scalar division ring of its closed kernel dual. (Contributed by NM, 25-Mar-2015.)

Hypothesis

Ref	Expression
hgmapval.h	⊢ 𝐻 = (LHyp‘𝐾)

Assertion

Ref	Expression
hgmapffval	⊢ (𝐾 ∈ 𝑋 → (HGMap‘𝐾) = (𝑤 ∈ 𝐻 ↦ {𝑎 ∣ [((DVecH‘𝐾)‘𝑤) / 𝑢][(Base‘(Scalar‘𝑢)) / 𝑏][((HDMap‘𝐾)‘𝑤) / 𝑚]𝑎 ∈ (𝑥 ∈ 𝑏 ↦ (℩𝑦 ∈ 𝑏 ∀𝑣 ∈ (Base‘𝑢)(𝑚‘(𝑥( ·𝑠 ‘𝑢)𝑣)) = (𝑦( ·𝑠 ‘((LCDual‘𝐾)‘𝑤))(𝑚‘𝑣))))}))

Distinct variable groups:   𝑤,𝐻   𝑎,𝑏,𝑚,𝑢,𝑣,𝑤,𝑥,𝑦,𝐾

Allowed substitution hints:   𝐻(𝑥,𝑦,𝑣,𝑢,𝑚,𝑎,𝑏)   𝑋(𝑥,𝑦,𝑤,𝑣,𝑢,𝑚,𝑎,𝑏)

Proof of Theorem hgmapffval

Dummy variable 𝑘 is distinct from all other variables.
