Ref Expression
mapdfval ((𝐾𝑋𝑊𝐻) → 𝑀 = (𝑠𝑆 ↦ {𝑓𝐹 ∣ ((𝑂‘(𝑂‘(𝐿𝑓))) = (𝐿𝑓) ∧ (𝑂‘(𝐿𝑓)) ⊆ 𝑠)}))
Distinct variable groups:   𝑓,𝑠,𝐾   𝑓,𝐹   𝑆,𝑠   𝑓,𝑊,𝑠
Allowed substitution hints:   𝑆(𝑓)   𝑈(𝑓,𝑠)   𝐹(𝑠)   𝐻(𝑓,𝑠)   𝐿(𝑓,𝑠)   𝑀(𝑓,𝑠)   𝑂(𝑓,𝑠)   𝑋(𝑓,𝑠)

Proof of Theorem mapdfval
Dummy variable 𝑤 is distinct from all other variables.
