Theorem mapdffval 41010

Description: Projectivity from vector space H to dual space. (Contributed by NM, 25-Jan-2015.)

Hypothesis

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

Assertion

Ref	Expression
mapdffval	⊢ (𝐾 ∈ 𝑋 → (mapd‘𝐾) = (𝑤 ∈ 𝐻 ↦ (𝑠 ∈ (LSubSp‘((DVecH‘𝐾)‘𝑤)) ↦ {𝑓 ∈ (LFnl‘((DVecH‘𝐾)‘𝑤)) ∣ ((((ocH‘𝐾)‘𝑤)‘(((ocH‘𝐾)‘𝑤)‘((LKer‘((DVecH‘𝐾)‘𝑤))‘𝑓))) = ((LKer‘((DVecH‘𝐾)‘𝑤))‘𝑓) ∧ (((ocH‘𝐾)‘𝑤)‘((LKer‘((DVecH‘𝐾)‘𝑤))‘𝑓)) ⊆ 𝑠)})))

Distinct variable groups:   𝑤,𝐻   𝑓,𝑠,𝑤,𝐾

Allowed substitution hints:   𝐻(𝑓,𝑠)   𝑋(𝑤,𝑓,𝑠)

Proof of Theorem mapdffval

Dummy variable 𝑘 is distinct from all other variables.
