Theorem ltrnfset 36797

Description: The set of all lattice translations for a lattice 𝐾. (Contributed by NM, 11-May-2012.)

Hypotheses

Ref	Expression
ltrnset.l	⊢ ≤ = (le‘𝐾)
ltrnset.j	⊢ ∨ = (join‘𝐾)
ltrnset.m	⊢ ∧ = (meet‘𝐾)
ltrnset.a	⊢ 𝐴 = (Atoms‘𝐾)
ltrnset.h	⊢ 𝐻 = (LHyp‘𝐾)

Assertion

Ref	Expression
ltrnfset	⊢ (𝐾 ∈ 𝐶 → (LTrn‘𝐾) = (𝑤 ∈ 𝐻 ↦ {𝑓 ∈ ((LDil‘𝐾)‘𝑤) ∣ ∀𝑝 ∈ 𝐴 ∀𝑞 ∈ 𝐴 ((¬ 𝑝 ≤ 𝑤 ∧ ¬ 𝑞 ≤ 𝑤) → ((𝑝 ∨ (𝑓‘𝑝)) ∧ 𝑤) = ((𝑞 ∨ (𝑓‘𝑞)) ∧ 𝑤))}))

Distinct variable groups:   𝑞,𝑝,𝐴   𝑤,𝐻   𝑓,𝑝,𝑞,𝑤,𝐾

Allowed substitution hints:   𝐴(𝑤,𝑓)   𝐶(𝑤,𝑓,𝑞,𝑝)   𝐻(𝑓,𝑞,𝑝)   ∨ (𝑤,𝑓,𝑞,𝑝)   ≤ (𝑤,𝑓,𝑞,𝑝)   ∧ (𝑤,𝑓,𝑞,𝑝)

Proof of Theorem ltrnfset

Dummy variable 𝑘 is distinct from all other variables.
