Hypothesis
Ref Expression
hvmapval.h 𝐻 = (LHyp‘𝐾)
Assertion
Ref Expression
hvmapffval (𝐾𝑋 → (HVMap‘𝐾) = (𝑤𝐻 ↦ (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.
