Theorem lineset 38912
Description: The set of lines in a Hilbert lattice. (Contributed by NM, 19-Sep-2011.)
Hypotheses
Ref Expression
lineset.l ≀ = (leβ€˜πΎ)
lineset.j ∨ = (joinβ€˜πΎ)
lineset.a 𝐴 = (Atomsβ€˜πΎ)
lineset.n 𝑁 = (Linesβ€˜πΎ)
Assertion
Ref Expression
lineset (𝐾 ∈ 𝐡 β†’ 𝑁 = {𝑠 ∣ βˆƒπ‘ž ∈ 𝐴 βˆƒπ‘Ÿ ∈ 𝐴 (π‘ž β‰  π‘Ÿ ∧ 𝑠 = {𝑝 ∈ 𝐴 ∣ 𝑝 ≀ (π‘ž ∨ π‘Ÿ)})})
Distinct variable groups:   π‘ž,𝑝,π‘Ÿ,𝑠,𝐴   𝐾,𝑝,π‘ž,π‘Ÿ,𝑠   ∨ ,𝑠   ≀ ,𝑠
Allowed substitution hints:   𝐡(𝑠,π‘Ÿ,π‘ž,𝑝)   ∨ (π‘Ÿ,π‘ž,𝑝)   ≀ (π‘Ÿ,π‘ž,𝑝)   𝑁(𝑠,π‘Ÿ,π‘ž,𝑝)

Proof of Theorem lineset
Dummy variable π‘˜ is distinct from all other variables.
