Hypotheses

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

Assertion

Ref	Expression
dicval	⊢ (((𝐾 ∈ 𝑉 ∧ 𝑊 ∈ 𝐻) ∧ (𝑄 ∈ 𝐴 ∧ ¬ 𝑄 ≤ 𝑊)) → (𝐼‘𝑄) = {⟨𝑓, 𝑠⟩ ∣ (𝑓 = (𝑠‘(℩𝑔 ∈ 𝑇 (𝑔‘𝑃) = 𝑄)) ∧ 𝑠 ∈ 𝐸)})

Distinct variable groups:   𝑓,𝑔,𝑠,𝐾   𝑇,𝑔   𝑓,𝑊,𝑔,𝑠   𝑓,𝐸,𝑠   𝑃,𝑓   𝑄,𝑓,𝑔,𝑠   𝑇,𝑓

Allowed substitution hints:   𝐴(𝑓, 𝑔, 𝑠)   𝑃(𝑔, 𝑠)   𝑇(𝑠)   𝐸(𝑔)   𝐻(𝑓, 𝑔, 𝑠)   𝐼(𝑓, 𝑔, 𝑠)   ≤ (𝑓, 𝑔, 𝑠)   𝑉(𝑓, 𝑔, 𝑠)

Proof of Theorem dicval

Dummy variables 𝑟 𝑞 are mutually distinct and distinct from all other variables.
