Theorem hvmapffval 41752

Description: Map from nonzero vectors to nonzero functionals in the closed kernel dual space. (Contributed by NM, 23-Mar-2015.)

Hypothesis

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

Assertion

Ref	Expression
hvmapffval	⊢ (𝐾 ∈ 𝑋 → (HVMap‘𝐾) = (𝑤 ∈ 𝐻 ↦ (𝑥 ∈ ((Base‘((DVecH‘𝐾)‘𝑤)) ∖ {(0g‘((DVecH‘𝐾)‘𝑤))}) ↦ (𝑣 ∈ (Base‘((DVecH‘𝐾)‘𝑤)) ↦ (℩𝑗 ∈ (Base‘(Scalar‘((DVecH‘𝐾)‘𝑤)))∃𝑡 ∈ (((ocH‘𝐾)‘𝑤)‘{𝑥})𝑣 = (𝑡(+g‘((DVecH‘𝐾)‘𝑤))(𝑗( ·𝑠 ‘((DVecH‘𝐾)‘𝑤))𝑥)))))))

Distinct variable groups:   𝑤,𝐻   𝑡,𝑗,𝑣,𝑥,𝑤,𝐾

Allowed substitution hints:   𝐻(𝑥,𝑣,𝑡,𝑗)   𝑋(𝑥,𝑤,𝑣,𝑡,𝑗)

Proof of Theorem hvmapffval

Dummy variable 𝑘 is distinct from all other variables.
