Hypothesis
Ref Expression
mapdval.h 𝐻 = (LHyp‘𝐾)
Assertion
Ref Expression
mapdffval (𝐾𝑋 → (mapd‘𝐾) = (𝑤𝐻 ↦ (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.
