Theorem dicffval 42055

Description: The partial isomorphism C for a lattice 𝐾. (Contributed by NM, 15-Dec-2013.)

Hypotheses

Ref	Expression
dicval.l	⊢ ≤ = (le‘𝐾)
dicval.a	⊢ 𝐴 = (Atoms‘𝐾)
dicval.h	⊢ 𝐻 = (LHyp‘𝐾)

Assertion

Ref	Expression
dicffval	⊢ (𝐾 ∈ 𝑉 → (DIsoC‘𝐾) = (𝑤 ∈ 𝐻 ↦ (𝑞 ∈ {𝑟 ∈ 𝐴 ∣ ¬ 𝑟 ≤ 𝑤} ↦ {⟨𝑓, 𝑠⟩ ∣ (𝑓 = (𝑠‘(℩𝑔 ∈ ((LTrn‘𝐾)‘𝑤)(𝑔‘((oc‘𝐾)‘𝑤)) = 𝑞)) ∧ 𝑠 ∈ ((TEndo‘𝐾)‘𝑤))})))

Distinct variable groups:   𝐴,𝑟   𝑤,𝐻   𝑓,𝑔,𝑞,𝑟,𝑠,𝑤,𝐾

Allowed substitution hints:   𝐴(𝑤, 𝑓, 𝑔, 𝑠, 𝑞)   𝐻(𝑓, 𝑔, 𝑠, 𝑟, 𝑞)   ≤ (𝑤, 𝑓, 𝑔, 𝑠, 𝑟, 𝑞)   𝑉(𝑤, 𝑓, 𝑔, 𝑠, 𝑟, 𝑞)

Proof of Theorem dicffval

Dummy variable 𝑘 is distinct from all other variables.
